Abrégé

The invention relates to a connecting assembly for connecting a pipe (1) with a connecting element (2) which comprises a conical bore (6) that tapers starting from a face (5). Said connecting assembly comprises: a longitudinal axis, a pipe (1) that can be inserted in the conical bore (6) of the connecting element (2), a supporting ring (15) that has a conical bore (18) flared in the same direction as the conical bore (6) of the connecting element (2), starting from a first retaining surface (37), and that is supported on the face (5) of the connecting element (2) with a second retaining surface (17), and a a union nut (10) that can be screwed onto a thread (4) of the connecting element (2), configures a tensioning surface (13) and is at least indirectly supported by the supporting ring (15) in the axial direction, a cutting ring (19) that is seated in the conical bore (18) of the supporting ring (15), has a pressure surface (25) to be impinged upon by the tensioning surface (13) of the union nut (10) and has at least one first cutting edge (23), and a collar in the external face of the pipe (1), produced when the first cutting edge (23) cuts into the pipe (1), the outer diameter thereof being larger than the smallest internal diameter of the supporting ring (15) and the collar being disposed between the first pipe end and the first retaining face (37).

• F16L 19/06 - Raccords dans lesquels les surfaces d'étanchéité sont maintenues en contact par un organe, p. ex. un écrou à oreilles vissé dans, ou vissé sur une des parties du raccord dans lesquels le serrage radial est obtenu par une action de coincement entre les extrémités non déformées du tuyau
• F16L 19/08 - Raccords dans lesquels les surfaces d'étanchéité sont maintenues en contact par un organe, p. ex. un écrou à oreilles vissé dans, ou vissé sur une des parties du raccord avec segments métalliques qui mordent dans la paroi du tuyau

The invention relates to a connecting assembly for connecting a pipe (1) or a pipe stub with a connecting element (2) which comprises a conical bore (6) that tapers starting from a face (5). Said connecting assembly comprises: a longitudinal axis (6), a union nut (10) that can be screwed onto a thread (4) of the connecting element (2) and configures a tensioning surface (13), a supporting ring (15) that has a conical bore (18) tapering in the same direction as the conical bore (6) of the connecting element (2) and that is supported on the face (5) of the connecting element (2) when mounted, and a cutting ring (19) that is seated in the conical bore (18) of the supporting ring (15), has a pressure surface (25) to be impinged upon by the tensioning face (13) of the union nut (10) and that is supported on the supporting ring (15) in the radial direction towards the longitudinal axis (3).
