Abstract: A spring clip includes two articulated legs having engagement tongues for engagement with an external thread of a threaded shank, and at least one spring leg extending away from a base plate and arranged on a side of the base plate opposite the articulated legs. Engagement of the engagement tongues with the external thread is improved by the spring force exerted by the spring legs. Manipulation tongues are provided for assembly and disassembly of the spring clip, and ensure torque-free handling of the spring clip.

Abstract: A device for securing an add-on to a support comprises a back wall (3) and a front wall arrangement (14) which is resilient with respect to the back wall (3) and which, when the device is arranged as intended, comes into engagement with an insertion opening provided in an edge region of the support. The device according to the invention comprises a manipulation structure (15, 16, 21) by which, to release the engagement, the front wall arrangement (14) can be moved toward the back wall (3) with the aid of a tool that is introduced through a tool channel (22).

Abstract: A device for fastening an add-on part to a support part is equipped with a fastening bracket, which has a flat cover plate and, at opposite sides, bracket arms which are attached to the cover plate, and with a bearing part which can be connected to the fastening bracket. The bearing part has a receiving space in which the cover plate of the fastening bracket is mounted so as to be rotatable between a locking position, in which the bracket arms engage behind the support part, and a release position in which the bracket arms are not in engagement with the support part. In this way, an add-on part can be connected to and disconnected again from a support part in an efficient and reliable manner.

Abstract: A device according to the invention for fastening an add-on part (2) to a support part is equipped with a fastening bracket (11), which has a flat cover plate (12) and bracket arms that are joined to opposite sides of said cover plate (12), and with a bearing part (1) that can be connected to the fastening bracket (11). The bearing part (1) has a receiving space (6) in which the cover plate (12) of the fastening bracket (11) is mounted so as to be rotatable between a locking position, in which the bracket arms engage behind the support part, and a releasing position, in which the bracket arms are out of engagement with the support part. In this way, an add-on part can be connected to and disconnected again from a support part in an efficient and reliable manner.

Abstract: A device for fastening a sensor to a support part comprises a sensor mount (1). The sensor mount (1) is made of sheet metal and comprises a base plate (2) as well as a counter plate (5), which is placed at a distance from the base plate (2) while being joined thereto. The area of the base plate (2) is greater than the area of the counter plate (5). Indexing means (18, 19, 20) are formed on the counter plate (5) in order to ensure, together with counter means formed on the sensor, the insertion of the sensor into the sensor mount (1) at a correct angle. This device is characterized, with a precise pre-alignment of the sensor, by having a particularly low weight.

Abstract: A device for fastening an attachment to a support part has a clamp (1) which has a base plate (2) and two leg arrangements arranged on opposite sides of the base plate (2) and having inner legs (5, 6) and outer legs (9, 10). Furthermore, there is an engagement unit having a bearing piece (14) that can be connected to the attachment and having a locking part (26) displaceably mounted in the bearing piece (14). The locking part (26) has at least two locking feet (29) and is arranged free of effective engagement relative to the clamp (1) in a release position and is in engagement with the clamp (1) in a locking position with the locking feet (29) in such a way that at least one respective locking foot (29) blocks a movement of an outer leg (9, 10) in the direction of the inner leg (5, 6) connected to it. As a result, very reliable manipulation and high pull-out strength are achieved.

Abstract: A spring nut to be fastened to a bolt comprises a frame (1) to which are attached two mutually opposite resilient clamping legs (5, 6). Also present is a locking leg (9), which is attached by one end bendably about1 the frame (1) and which in a closed position comes into engagement with a holding arrangement (13, 14). In the closed position, the locking leg (9) exerts on at least one clamping leg (5, 6) a closing force that leads to a holding force holding the spring nut on the bolt. As a result, despite relatively high nominal holding forces, the mating and withdrawal forces for mating the spring nut onto and removing it from the bolt are comparatively low.

Abstract: Disclosed is a clamp for joining an add-on piece (20) to a base (19). Said clamp comprises a base plate (1) and an opposite plate (5) which lies across from the base plate (1), is joined thereto via at least one connecting web (3), and is provided with an engaging arrangement (7, 8) that can be engaged with a fastening part (22). At least one pressing clip (9) is also provided. Said pressing clip (9) rests against the base (19) on the side facing the base plate (1) when the clamp is slid on the base (19). The or each pressing clip (9, 10) is attached to the side of the opposite plate (5) which faces the or each connecting web (3) while an inclined section (13) thereof extends to the base plate (1) such that a relatively great tolerance regarding the thickness of the base (19) is obtained while handling the clamp during mounting and removing is unproblematic.
