Connecting and functional parts connecting unit for use in e.g. motor vehicle, has wedge intermediate piece cooperating with its outer and inner surfaces such that surfaces run with respect to inserting direction in slightly inclined manner

摘要

The part has an external thread and a screw sleeve fixing functional and connecting parts under relative axial movement between a plug-in unit and a receiving hull. A wedge intermediate piece (24) cooperates with its outer surfaces with polygonal inner surfaces of the hull and with its inner surfaces with polygonal outer surfaces of the unit such that the surfaces run with respect to an inserting direction in a slightly inclined manner.
