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: Connector assembly, and/or motor-vehicle connector assembly, with at least one connector and at least one media line connected to the connector. The media line is electrically heated, a heat-conducting element being arranged in the transition region between connector and media line. The heat-conducting element extends with a first heat-conducting section into the media line and with a second heat-conducting section into the connector. By means of the electric heating of the media line, the heat-conducting element is heated, and/or indirectly heated, and in particular is heated and/or indirectly heated as far as the region of the connector.

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.
