には略半円断面環状であって該対向端部と同軸のシール
面が形成されている。A connector is used in a fluid transport system such as a pipe for transporting toxic gas. The connector includes two annular pieces that are secured, such as by welding, to two opposite ends of a tubular body to be joined. These annular pieces have a collar which forms a radial surface, which has a substantially semi-circular cross-section and a sealing surface which is coaxial with the opposite end.

を有する。In the connector according to the present invention, at least one radial surface of the end piece of the tubular body terminates in an annular radial plane near the inner wall surface of the end piece, and further extends outward. The end piece has a quasi-line formed of a coaxial arc, and forms an annular projection forming a rotation surface having a generatrix inclined with respect to the longitudinal axis of the end piece. Further, the metal seal of the connector according to the present invention has a cylindrical inner wall having the same diameter as the inner wall surface of the end piece, and further has at least one radial surface extending from the cylindrical inner wall and an annular radius of the end piece. The directional plane has an annular plane to which it abuts, and has a rotating surface complementary to the rotating surface of the end piece towards the outside of the sealing portion.
