  • Patent number: 6695355
    Abstract: A pipe fitting element comprises a tubular fit-in sleeve (1) which can be fitted into an end of a pipe (2) to be connected, and a clamping ring nut (10), coaxial to the sleeve (1). The pipe (2) is arranged to be clamped by tightening the ring nut (10) on the sleeve (1) and translating it towards the pipe (2) while drawing two clamping surfaces (5, 13) mutually closer. One of the surfaces is situated on the outer surface of the sleeve (1) and the other situated on the inner surface of the ring nut (10). These clamping surfaces (5, 13) consist of progressive widening (105, 113) of the outside diameter of the sleeve (1) and of the inside diameter of the end of the ring nut (10) turned towards the pipe (2). A pipe joint, which has at each end a pipe fitting element of the above described type is also provided.
