Abstract: The invention relates to a coupling for a fluid line, wherein an oscillating circuit (5, 9) is present for detecting a properly closed position of an inserted part (13). A tuning device (19) is further provided, by means of which the resonant frequency of the oscillating circuit (5, 9) can be influenced such that the resonant frequency corresponds to a characteristic closure frequency only in the closed position of the insertion part (13). The proper arrangement of the insertion part (13) in the closed position can thereby be detected without contact.

Abstract: In a fastening element (1) comprised of a holding part (2) configured with a support plate (4) and expanding cheeks (5) and of a locking part (3) that is guided displaceably in said holding part (2), formed adjacent the support plate (4) are cantilevered walls (16) that are offset radially outwardly with respect to a guide wall (13), which, in order to guide the locking part (3), bears flush against the shaft portion (6). As a result, the locking part (3) can be pushed along substantially without force until it reaches inwardly protruding ramp projections (14) formed on the expanding cheeks (5), even when said expanding cheeks (5) are flexed inward, and with the advantage of a better lever ratio for spreading the expanding cheeks (5).

Abstract: A fastening device to be fitted into a support part (22) has a cover plate (1) and two clamping arms (6, 7). Each clamping arm (6, 7) has an inner leg (5) and an outer leg (10) which has a bracing structure on its end facing the cover plate (1). The bracing structure of each clamping arm (6) is provided with two flat side cheeks (15, 16) that are joined to mutually opposite side margins (13, 14) of the respective outer leg (10) and extend toward the other clamping arm (6, 7). Each side cheek (15, 16) has an end face (17) that is oriented at an angle to the cover plate (1) and falls away toward the respective outer leg (10) from the end remote from that outer leg (10). The fastening device according to the invention can consequently be used in the presence of relatively high extraction forces with support parts that vary in thickness over a relatively large range.

Abstract: For fastening a coupling (1) formed from one plug-in part (2) and one sliding part (4) to a carrier part, a retaining arrangement (9) constructed of at least one side part (10, 11) from each opposite side is proposed. Each of the side parts (10, 11) has a spring arm (20) to which a bracket (23) is attached that grips the shaped collar (6) of the plug-in part (2) from behind in such a way that the collar (6), after pushing in the plug-in part (2) from the entry side (14), is in contact with a termination rib (24). Thus the plug-in part (2) is left fixed on the carrier part without both parts (2, 4) of the coupling (1) having to be plugged together when the sliding part (4) is slid.

Abstract: An engagement unit for insertion on and engagement with a threaded bolt (33) is provided with an inner part (1) and with an outer part (2) that can be slid onto the inner part (1). The inner part (1) and the outer part (2) are configured with torque receiving means (8, 9, 23, 24) for transmitting a torque applied to the outer part (2) to the inner part (1). After the inner part (1) has been slid onto a threaded bolt (33) in a pre-assembly arrangement in which latching means configured on spring arms of the inner part (1) and cooperating with the threaded bolt (33) are able to slide along the threaded bolt (33), the engagement unit according to the invention can thus be inserted onto the threaded bolt (33) and, once the outer part (2) has been slid onto the inner part (1), can be tightened in the manner of a screw.

Abstract: A mounting unit (1) serves to rotatably and captively fasten a screw (2) to a mounting part (3), especially the fastening eyelet (4) of a belt buckle of an automobile, a truck or a different commercial vehicle. The mounting unit (1) includes a screw (2) including a head (5), a shank portion (6) and a threaded portion (7) including a thread (8), the shank portion (6) being arranged in a region between the head (2) and the threaded portion (7).

Abstract: A coupling comprising a receiving part (1), a securing part (9) and an insertion part (17) includes blocking elements (6, 13?) whose engagement preventing the securing part (9) from moving from an extended position into a retracted position is released by the axial displacement of latching arms (13) of the securing part (9) under the effect of a retaining ring (22) upon the insertion of said insertion part (17), such that when the insertion part (17) is properly arranged in a receiving space (16) of the receiving part (1), the securing part (9) can be shifted into the retracted position in which said insertion part (17) is secured. What is achieved in this way is relatively simple modification of the assembly force through design measures, high wear resistance, and simple and operationally reliable manipulation of the inventive coupling with regard to the release of the connection between the receiving part and the insertion part, especially under confined spatial conditions.

Abstract: The invention relates to a fixing device comprising a closing part (8) which comprises a head plate (9) and a base shaft (11) equipped with clips (24). Spring webs are arranged on the base shaft (11) whereon a clip (24) is arranged, webbed wings are formed and journals are embodied. The receiving element (12) also comprises an edge wall (14) which is fitted with projecting sections and recesses, in addition to a profile surface. When the closing part is in the mounted state, the journals are arranged in a first recess and the spring webs are in a rear engaging position, wherein the clips engage behind the component (3). When the closing part (8) is in the demounted state, the journals are arranged in a second recess and the spring webs in a released position, wherein the journals are arranged in an engaging-free manner in relation to the rear engaging position. As a result, the components (1, 2, 3) are clipped together and can be detached from each other in a very simple manner.

Abstract: In an apparatus for wetting a glass pane, in particular a glass pane of a motor vehicle, a spherical body (15) which supports a nozzle body (20) is inserted into an accommodation space (10) which is formed in a bearing head (9) of an insert body (1). The accommodation space (10) exhibits the spherical body (15) together with resistance projections (12) which fix an annular shoulder and also serve to fluidically stabilize a liquid fluid, which flows into a flow expansion space as a subregion of the accommodation space (10), in the form of, for example, wash water. An oscillating fan-like stream can be reliably generated as a result.

Abstract: The invention relates to a device for subjecting an object to the action of a liquid, for example, a window pane of a motor vehicle with a cleaning liquid, with a retaining body (1), which can be connected to a liquid line arrangement, and with a nozzle body (12). The nozzle body (12) is provided with a cylindrical design and can be inserted into a location space (8) of the retaining body (1) whereby being rotationally mounted therein. Rotating the nozzle body (12) about the cylinder axis permits a liquid jet or liquid fan to be adjusted with regard to its outlet angle, this liquid jet or fan exiting via an outlet end (18), which is formed in the nozzle body (12), and via an outlet recess (7) formed inside the retaining body (1). A long serviceable life is achieved due to this cylindrical design.

Also present is a spring arm (13), which is connected to one side wall (10) and extends in the direction of the opposite side wall (9) and is able to pivot resiliently toward and away from the base plate (6) within a flexion zone (15). Configured on the spring arm (13) are an engaging claw (16) that extends in the direction of the base plate (6) and is configured to engage in a locking recess (17) introduced into at least one end flange, and a releasing element that extends away from the base plate (6). The pipes can thus be disconnected with relative ease.

Abstract: A device for fastening a rectangular sensor to a support part has a base plate (2) in which a receiving recess (3) is made. Guide walls (6, 7) are integrally formed on mutually opposite edge sides (4, 5) of the receiving recess (3), said guide walls extending between two corner regions (18, 20; 19, 21) of the receiving recess (3), which corner regions end an edge side (4, 5). Furthermore, stop parts (10, 11) which are shorter than the length of the guide walls (6, 7) are integrally formed on the other edge sides (8, 9), in each case in the central region thereof, the stop parts each having at least one stop section (26) oriented at right angles to the base plate (2), wherein the guide sections (22) and the stop sections (26) bear against a wall of the sensor when the sensor is fitted. As a result, even sensors of relatively large dimensions can be fastened to the support part in a stable and accurately fitting manner with relatively little expenditure on material.

Abstract: For fastening a coupling (1) formed from one plug-in part (2) and one sliding part (4) to a carrier part, a retaining arrangement (9) constructed of at least one side part (10, 11) from each opposite side is proposed. Each of the side parts (10, 11) has a spring arm (20) to which a bracket (23) is attached that grips the shaped collar (6) of the plug-in part (2) from behind in such a way that the collar (6), after pushing in the plug-in part (2) from the entry side (14), is in contact with a termination rib (24). Thus the plug-in part (2) is left fixed on the carrier part without both parts (2, 4) of the coupling (1) having to be plugged together when the sliding part (4) is slid.

Abstract: The invention relates to a device for attaching two add-on parts (36, 37) to a carrier part (35), said device having an outer clamp (1) and an inner clamp (11) that arrests any movement of the outer clamp (1), said clamps being insertable, in an interlocked arrangement, into a single insertion opening configured in the carrier part (35) so as to hold not only an add-on part (37) that is movable relative to the carrier part (35), but also the additional add-on part (36), on the carrier part (35) with a high extraction force for each.

Abstract: A device for fastening an add-on part, which is formed with tongue-like projections, to a support part has members (1, 2) which are connected to one another. At least a number of the members (1, 2) has a cage wall (3) which surrounds a receiving space (14) and on which is formed a ramp structure (13) which projects into the receiving space (14) and has an inclined piece, which rises obliquely from an inlet side to an outlet side of the respective member (1, 2), and a stop piece. The stop piece has a greater spacing from a contact side of the cage wall (3) than that region of the inclined piece which is adjacent to the inlet side. In this way, when the ramp structure (13) is in engagement with pins which are attached to the support part, the members (1, 2) press against the tongue-like projections and fasten the add-on part to the support part.

Abstract: The invention relates to a method for directly joining two end sections (3, 4) of corrugated pipes (1, 2), comprising the following steps: inserting the end sections (3, 4) of the corrugated pipes (1, 2) into a preferably inventive heat-shrinkable sleeve arrangement (8, 9); subjecting the heat-shrinkable sleeve arrangement (8, 9) to heat in the area of the end sections (3, 4) of the corrugated pipes (1, 2) so that the heat-shrinkable sleeve arrangement (8, 9) rests against the outside wall of the end sections (3, 4) of the corrugated pipes (1, 2), and; stress-free cooling the heat-shrinkable sleeve arrangement (8, 9) and the end sections (3, 4) of the corrugated pipes (1, 2) to a temperature at which the connection can be mechanically stressed. This enables end sections (3, 4) of corrugated pipes (1, 2) to be joined to one another easily and in a cost-effective manner.

Abstract: An apparatus for setting fastening elements (5) has a feed drive (21), by means of which the connecting elements (5) can be fed to an installation position, and a setting device which has a setting tool and by means of which a fastening element (5) arranged in the installation position can be ejected to come into engagement with a support part.
