Abstract: A motor vehicle assembly unit having a connector, in particular a quick connector, and having a motor vehicle fluid line, wherein the connector includes an insertion end for inserting the fluid line, wherein there is a securing spike on the insertion end, which is encompassed by an outer sleeve. An annular insertion space for the fluid line or a fluid line end of the fluid line is disposed between the securing spike and the outer sleeve. The outer sleeve is connected to the securing spike by means of at least one break-away element, that breaks when the fluid line is inserted in the annular insertion space, such that the outer sleeve can be slid onto the securing spike, or further slid onto the securing spike from, or with, the fluid line.

Abstract: A quick release coupling for connecting at least two connecting elements of a fluid system for a liquid medium, and comprises a coupling body, defining a flow channel between a first connecting end for the connection of a first connecting element, and a second connecting end. The coupling body includes a sensor chamber separated from the flow channel by a separating wall. At least one sensor is disposed in the sensor chamber, wherein a sensor probe is connected to the sensor, which extends through the separating wall from the sensor such that an end of the sensor probe facing the flow channel is in communication with the flow channel. The coupling body rests against the sensor probe without a seal. The sensor probe is a capillary tube and could be made of glass.

Abstract: A quick connector for making a releasable connection in a fluid line with a connector body, a male member, a retainer and a verification element. The connector body comprises a through bore, wherein the male member introduced into the through bore is releasably fixable in the through bore by the retainer. The retainer comprises a ring and the verification element has an annular body. The annular body of the verification element can be displaced in an axial direction with respect to the through bore from an initial open position to a verification position when the male member is secured by the retainer in the through bore to place the verification element in a verification and locked position. In one form, the retainer includes lifting arms pivotably attached within coupling openings which cooperate with the coupling projections of the verification element to permit axial translation of the verification element to the verification position when the male member is fully inserted into the through bore.

Abstract: A connector for connecting at least two receptor modules for a liquid medium, wherein the connector has a first connection end for the connection to a first receptor module and a second connection end for the connection to a second receptor module. The connector has a pressure equalization chamber between the first and second connection ends, in which a compressible insert is disposed. The compressible insert lies in part against the interior wall of the pressure equalization chamber. A least one longitudinal channel for a fluid communication between the first and second connection ends is provided between the interior wall of the pressure equalization chamber and the compressible insert. The compressible insert can be compacted as a result of a volume expansion of the liquid medium due to temperature conditions.

Abstract: Quick connector coupling having a connector body to receive a male member with a radial upset comprised of two separate, interconnected components, a head element and a sealing element which define a through-hole from a male member entry port at the end of the head element axially to an exit port at the end of the sealing element. A retainer for releasably securing the male member to the connector body is ring-shaped, and encircles the connector body head element. It includes at least one retainer element, which reaches through a window in the head element and interacts with the radial upset of the male member to secure the male member in the connector body.

Abstract: A motor vehicle hose consisting of plastic material, where the interior surface of the hose consists at least in segments of an electrically conducting plastic material. The invention provides for a section of electrically conducting plastic material that extends at least over a portion of the circumference of the hose and which is connected to the electrically conducting interior surface of the hose. The section extends in a radial direction into a layer of non-conducting plastic material. The section extends at least in segments in the longitudinal direction of the hose.

Abstract: A method of grounding a tube to a chassis wherein a plastic clip made conductive by the incorporation of conductive particles therein, is clamped onto the jacket of metal automotive vehicle tubing so that projections on the clip penetrate through the jacket to engage the outer surface of the metal tube. The clip body is welded to the jacket to hermetically seal the region of contact between the clip and the metal.

Abstract: An automotive fluid tubing, especially for gasoline, diesel fuel or hydraulic fluid, and composed of metal can be provided with a tube coating of aluminum and then a polyamide 12 layer which is extruded onto the aluminum coating. The polyamide extruded layer greatly improves the wear-resistance and corrosion-resistance of the tubing.

Abstract: A tube end having an outwardly projecting ridge is secured in a fitting having a body formed with a seat centered on an axis and open axially rearwardly. The tube end is coaxially engageable in the seat, and a retaining clip on the body extends secantally across the seat and can move between an outer spread position engaging a respective inner surface of the seat and an inner retaining position spaced radially inward from the respective inner surface. The tube end when fully axially inserted in the seat is engaged axially outward of the ridge by the clip. A latch element can move between an outer freeing position generally clear of the clip and an inner locking position engaged outward of the clip between same and the respective inner surface and preventing the clip from moving from the inner retaining position to the outer spread position.
