The invention relates to a flange joint, comprising a pair of tubular pieces (1, 7) to be joined, a clamping flange (2, 9) mounted on each of the pieces (1, 7) to be joined, retaining means (10, 11) cooperating with the clamping flanges (2, 9) for joining said pieces (2, 7) together. At least one (2) of the clamping flanges is mounted in a rotation allowing manner on the respective piece (1) to be joined by effecting the mounting with a locking ring (3) fitted in a locking groove (4) formed in the piece (1) to be joined and in a complementary groove (5) formed in the clamping flange (2). The piece (1) to be joined has its locking groove (4) shaped to be relatively shallow and the clamping flange (2) has its complementary groove (5) shaped to extend in the clamping flange~s axial direction up to a front face (14) of the clamping flange, the complementary groove (5) expanding towards a junction between the pieces to be joined. The locking ring (3) is provided with a support member (13) which fits in the expanded portion of the clamping flange~s (2) groove (5), thus bearing against an external surface (15) of the piece (1) to be joined.
L'invention concerne un joint à brides comprenant une paire de pièces tubulaires (1, 7) à raccorder, une bride de serrage (2, 9) montée sur chacune des pièces à raccorder (1, 7), des moyens de retenue (10, 11) qui coopèrent avec les brides de serrage (2, 9) afin de raccorder les pièces précitées (2, 7) entre elles. Au moins l'une (2) des brides de serrage est montée de manière à permettre sa rotation sur la pièce respective (1) à raccorder, le montage étant effectué par emboîtement d'une bague de verrouillage (3) dans une rainure de verrouillage (4) formée dans la pièce (1) à raccorder et dans une rainure complémentaire (5) formée dans la bride de serrage (2). La pièce à raccorder (1) comprend une rainure de verrouillage (4) dont la forme est relativement peu profonde et la bride de serrage (2) comprend une rainure complémentaire (5) d'une forme qui lui permet de s'étendre dans la direction axiale de la bride de serrage jusqu'à un côté antérieur (14) de la bride de serrage, la rainure complémentaire (5) s'étendant vers une jonction entre les pièces à raccorder. La bague de verrouillage (3) comporte un organe de support (13) qui s'emboîte dans la partie étendue de la rainure (5) de la bride de serrage (2), prenant par conséquent appui contre une surface extérieure (15) de la pièce (1) à raccorder.
