Pipe connection coupling for heat exchanger in motor vehicles

摘要

The coupling has a connection socket (1) with pairs of passage apertures (6a,b). The front apertures have angled insertion faces (9a,b). The faces apply a forced movement in pipe insertion direction (R) to a plug-in fork during its insertion movement in insertion direction. The insertion faces have a front stop face, which is angled in insertion direction. The front apertures have insertion aids (11a,b).
