Plug-in connection for pipes with inner and outer parts

摘要

The inner part (1) has a pin (5) insertable into an opening in the outer part (2) and is locked by a radially deformable holder element (3) positioned in a cavity (17) in one of the connecting parts. There is a release chamber (26) for holding the holder element, adjacent to the cavity in one connecting part. The release chamber contains a blocking element (25). The cavity (22) in the other connecting part has a ramp (24) radially deforming the holder element fitting into the release chamber when the plug-in connection is undone. The holder element penetrates the release chamber so that the plug-in pin is pulled out of the opening (21) in the outer part.
