Abstract: A connecting device for media lines including a coupling element, an insert part and a fastening element. The coupling element has a connection opening and a fluid channel; the insert part can be inserted into the connection opening; and the insert part can be fastened to the coupling element by the fastening element. The fastening element also has at least one control surface. When the insert part is inserted into the connection opening under the action of an installation force, the insert part acts upon the control surface in such a way that the fastening element is moved against a restoring force. If the installation force is sufficient, the insert part slides past the control surface and the fastening element interlockingly locks the insertion part. If the installation force is not sufficient, the fastening element presses the insert part back out of the connection opening.

Abstract: A plug-type connector for media lines having a coupling part into which a plug part can be inserted. The plug part can be retainingly engaged in the coupling part by a retaining clip that has at least two pairs of spring arms. The clip can be premounted on the coupling part by latching of the spring arms. The clip is U-shaped wherein legs of the U-shape form the two pairs of spring arms, which pairs are arranged one behind the other in the longitudinal direction and are separated by a slot and are elastic in the radial and axial directions. The first pair of the spring arms interlockingly blocks the plug part against being pulling out of the coupling part, and the second pair of spring arms holds the retaining clip captively in the coupling part in pre-assembly and assembly positions.

Abstract: A line connector with two mutually separate flow paths for the connection of a pipe-in-pipe line. The line connector has an inner connecting element for connecting to an inner pipe of the pipe-in-pipe line, an outer connecting element for connecting to an outer pipe of the pipe-in-pipe line, a first attachment element for attachment of the first line to the inner pipe, and a second attachment element for attachment of the second line to the outer pipe. The inner connecting element and the first attachment element are integrally formed on a separate attachment part. The outer connecting element is integrally formed on a separate pipe adapter part. And, the second attachment element is integrally formed on a separate connecting sleeve. The connecting sleeve permits at both sides, in the unassembled state, being pushed over the outer pipe. The invention also relates to a line set including the line connector.

Abstract: A multi-line plug connector for connecting two heated fluid lines by way of a single connecting operation, including a female plug component which is connected with a male plug component. Each plug component includes a fluid connection and two electrical connections. Each plug component also includes an inner space in which a spectacle component is housed. The spectacle component has two guide channels for receiving electrical lines equipped with electrical contacts. The guide channels are connected with one another by a bridge that is fastened with a latching mechanism that secures the spectacle component against displacement along and/or obliquely to the coupling axis. The spectacle component receives a tubular fluid connector, connected with the spectacle component with form-fit and/or friction-fit, whereby the tubular fluid connector can be connected on one end to the heated fluid line and on the opposite end the fluid connector.

Abstract: A connection device for pipe lines includes a connection element that has a receiving opening for a pipe line and a retainer element that stops the pipe line from being pulled out. The retainer element is designed as a spring-elastic toothed ring that has teeth distributed across a circumference and which extend radially inward at an incline and act against the pipe line. The toothed ring is mounted to have limited axial play. At the transition region between an outer circumferential region and the retainer teeth, the toothed ring interacts with a circumferential tilt edge such that the toothed ring can pivot about the tilt edge out of a position in which its outer circumferential region is pressed against a first, lower contact section and a second, upper contact section. The retainer teeth being able to be elastically deformed by bending.

Abstract: A plug connection (1) for fluid lines, with two intermateable coupling parts (2, 3), which in an inserted state can be releasably locked via a locking device (4) consisting of two outer radial flange-like retaining ribs (21, 31) of the two coupling parts (2, 3), which are adjacent in an insertion direction (S) and axial (X-X) in inserted state and a retaining part (5) with an annular contour, which in preassembled state can be axially and radially fixed and undetachably assembled on one of the two coupling parts (3) and in an assembled state axially and radially encompasses the retaining ribs (21, 31) of the two coupling parts with at least one radially elastically moving retaining section (53) with a C-shaped axial section having two collars (51, 52). The plug connection incorporates features to ensure the undetachability of the retaining part (5) and minimize the space requirement, in particular during disassembly.

Abstract: A plug-in connection system for fluidic lines, fittings or assemblies, having a housing part and a plug part that can be plugged into a receiving opening of the housing part. A holding element on one of the coupling parts latches with a mating holding element on the other of the coupling parts. The holding element has a spreading surface that, by sliding relative to a corresponding surface of the plug part causes a spreading movement of the holding element, transversely with respect to an axis during installation. In order to improve the plug-in behavior during installation, a spreading contour of the spreading surface engages a mating contour in such a way that, while being plugged in, the spreading travel (Sw) of the holding element changes in a non-linear manner, depending on the status of installation.

Abstract: The present invention relates to a connector for fluid lines having of a coupling part that can be plugged together with a counter-coupling part along a plug-in axis. A locking device releasably locks the coupling part together with the counter-coupling part. The locking device includes a radially elastically deformable holding element held outside on the coupling part and at least partially encompassing it circumferentially. The holding element interacts with the coupling part, when positioned on the coupling part, via a fixation structure, such that said holding element can optionally be oriented in different relative rotational positions and be fixated in each case to prevent a free, unrestricted rotation about the plug-in axle (X) relative to the coupling part.

Abstract: A plug connection having two intermateable coupling parts that can be releasably locked via a locking device. The locking device includes a radial retaining bar on each of the coupling parts and a retaining part with a circumferentially closed annular contour. In a preassembled state, the retaining is undetachably assembled on one of the two coupling parts. In an assembled state, the retaining part axially and radially encompasses the retaining bars of both coupling parts. The retaining part includes an elastically moving retaining section having a C-shaped section defined by two collars. The collars have different sizes and/or shapes such that one collar releases an adjacent retaining bar upon the radial elastic outward movement out of the assembled state. The other collar remains engaged behind the retaining bar of the other coupling part.
