Abstract: A unit for connecting a fluid line to a port of a superordinate assembly, comprising a base body comprising a connection piece at one axial end for connection to the fluid line and a receiving portion at another axial end. The unit comprises an insert element comprising a resilient material and at least one radially outwardly projecting protrusion. The insert element defines, in its interior, an axial central connection opening and is separate from and connectable to the base body. The at least one protrusion projects into a corresponding aperture formed in an area of the receiving portion. Each protrusion comprises a blocking flank extending outwardly in a substantially radial direction and facing the axial end of the base body opposite the connection piece. The blocking flank is configured to abut against a respective blocking protrusion on the base body in a receiving portion engaged state of the insert element.

Abstract: A high-pressure fluid line including a corrugated tube defining a fluid flow channel its interior, wherein a wall of the corrugated tube, in parallel with the extension direction of the fluid flow channel, comprises a sequence of wave peaks and wave troughs. The fluid line includes a braiding made of threads, which is applied to an outer periphery of the corrugated tube. The braiding bears tightly against the outer periphery of the corrugated tube at a substantially constant braiding angle over the entire corrugated tube. The braiding and the corrugated tube are connected at least at two mutually separate locations such that stretching of the corrugated tube in a longitudinal direction is accompanied by a reduction in a diameter of the braiding.

Abstract: A receiving unit of a coupling device for fluid lines, and the coupling device. The receiving unit comprises a closure element which fluidically seals the fluid flow channel in a closed position. The closure element is preloaded into the closed position using a spring element. The closure element comprises a perforation-free cylindrical portion. The entire spring element, in the release position of the closure element, is arranged within a region that is completely overlapped by the cylindrical portion along the entire longitudinal extent thereof, as viewed in a radial direction of the cylindrical portion.

Abstract: The present invention relates to a device for controlling the temperature of a component and a method of production thereof. The device includes an elongate basic profile that defines a plurality of fluid flow channels in its interior. The fluid flow channels are arranged in series and separated by webs. The elongate basic profile extrudes from a plastic material. The device includes a connection unit connected to the basic profile and designed to direct fluid into the basic profile or out of the basic profile. The connection unit is formed partially or completely from a transparent plastic material.

Abstract: A connection unit for connecting fluid lines, including a plug-in unit connectable to a first fluid line not belonging to the connection unit, defining a first fluid flow channel in its interior, and a receiving unit connectable to a second fluid line not belonging to the connection unit, defining a second fluid flow channel in its interior. The plug-in unit and the receiving unit are connectable to establish a fluid connection between the first and second fluid flow channels. The connection unit also includes a release element transferrable from a holding state to a release state upon insertion of the plug-in unit into the receiving unit up to a predetermined depth, and an indicator element formed separately from the release element and locked by the release element in the holding state. The indicator element is detachable from the connection unit when the release element is in the release state.

Abstract: An attachment device, comprising a first line connector with a first fluid passage and a second line connector. The second line connector surrounds the first line connector such that a second fluid passage is created between the first line connector and the second line connector. The second fluid passage is fluidically separated from the first fluid passage. The second line connector can be pushed onto the first line connector from the end thereof situated opposite the hose attachment of the first line connector. The attachment is arranged in a line comprising the attachment device connected using a corresponding connection method.

Abstract: A connecting assembly (10) for connecting to a corrugated tube (12) includes a base body (14) with a receptacle recess (14a) for receiving the corrugated tube (12), and a latching unit (16) which can be introduced through a circumferential opening (14c) of the base body (14) into the receptacle recess (14a) and which has a latching element carrier (20) and a plurality of latching elements (22) constructed as one piece with the latching element carrier (20). The latching elements (22) are constructed for the purpose of engaging in a trough (12b) of the corrugated tube (12) and to resist a movement of the corrugated tube (12) out of the receptacle. The latching element carrier (20) is constructed as a split ring. The latching elements (22) are arranged uniformly distributed along the circumference of the latching element carrier (20).

Abstract: The invention relates to a plug-in connection for a first pipe and a second pipe and use thereof in a motor vehicle. A free end segment of the first pipe and a free end segment of the second pipe can be connected to each other. A retaining clip having two legs, which each bear a respective locking element, sits in a guide for the retaining clip, wherein the guide is formed on the free end segment of the first pipe. The retaining clip mounted in the guide interacts with the retaining region on the free end segment of the second pipe in a form-fitting and force-fitting manner by means of each of the locking elements.
