A tubular element has a sealing ring (10) mounted at an end of the tubular element (11). The sealing ring has a base (13) clamped against the outer surface of the tubular element. Further, the sealing ring has a sealing lip (14) adapted to seal against an inner surface of an outer tube (21), in which the tubular element is inserted. The base (13) is disposed in a groove (17) which is formed in the wall of the tubular element (11). The sealing ring (10) has a further lip (15) which is positioned adjacent to the end of the tubular element (11) and which is bent down and clamped against the base (13) by means of the end portion (18), thereby providing secure fastening of the sealing ring (10). The sealing ring (10) is fastened by a method involving bending of the end portion (18) of the tubular element (11) together with the further lip (15).
La présente invention concerne un élément tubulaire (11) comportant une bague d'étanchéité (10) à l'une de ses extrémités. Cette bague comporte une base (13) sertie sur la surface extérieure de l'élément tubulaire. Elle présente par ailleurs une lèvre d'étanchéité (14) qui se plaque sur la surface intérieure d'un tube extérieur (21), dans lequel l'élément tubulaire vient s'emboîter. La base (13) est logée dans une gorge (17) formée dans la paroi de l'élément tubulaire (11). La bague d'étanchéité (10) présente contre l'extrémité de l'élément tubulaire (11) une seconde lèvre (15) qui est rabattue et sertie contre la base (13) par l'extrémité terminale (18), ce qui maintient fermement la bague d'étanchéité (10). Pour fixer la bague d'étanchéité (10), on rabat la partie d'extrémité (18) de l'élément tubulaire avec la seconde lèvre (15).
