Abstract

In a connection between a pipe and a molding, a tubular housing, fixed on the molding, engages around the pipe with an inner wall tapering conically toward the free end of the housing. Arranged between the pipe and the housing inner wall is a clamping ring, which braces the pipe with the housing in a wedge-like manner. The clamping ring is held in its wedging functional position by a spring element acting on it in the axial direction. The spring element can be locked in a prestressed state without force acting on the clamping ring. To establish the connection between the pipe and the molding, a locking clip passing through the housing is pulled out of the housing to relax the spring element.
