摘要

Connecting assembly, has connecting body (2), with conical bore (6,18), which tapers starting from face (5). The connecting assembly comprises a longitudinal axis, a pipe (1), which inserts the connecting body with tube end (36) into the conical bore, a supporting ring (15), on basis of first retaining surface (37), has conical bore tapering in the same direction as the conical bore of the connecting element and has a second retaining surface (17). The second retaining surface is supported against the front surface of the connecting body. A union nut (10) can be screwed onto a thread (4) of the connecting element and configures a tensioning surface (13), and is supported indirectly axially against the supporting ring. A cutting ring (19) which is seated in the conical bore of the supporting ring has a pressure surface to be impinged upon by the tensioning face of the union nut and that is supported on the supporting ring and that has a first cutting edge (23). A band bulging (34) is formed in the exterior surface of the pipe by cutting the first cutting edge in the pipe and outside diameter of the pipe is larger than the smallest inside diameter of the supporting ring and is arranged between the tube end and the first retaining surface.
