Abstract

L'invention vise un élément de conduit tubulaire (1), notamment dévolu à un système d'échappement, qui comprend une première extrémité de raccordement, une seconde extrémité de raccordement, un évasement tronconique dans la région de ladite seconde extrémité de raccordement et, dans la région dudit évasement tronconique, un arrêt antirotation (5) réalisé de telle sorte qu'un élément de liaison, devant être prévu pour raccorder l'élément de conduit tubulaire (1) à un élément de conduit tubulaire additionnel, soit retenu sur ledit élément (1) avec verrouillage antirotation, à l'état de montage inachevé, dans la région de ladite seconde extrémité de raccordement.The invention relates to a tubular duct element (1), in particular assigned to an exhaust system, which comprises a first connection end, a second connection end, a frustoconical flare in the region of said second connection end and, in the region of said frustoconical flare, an anti-rotation stop (5) made such that a connecting element, to be provided for connecting the tubular duct element (1) to an additional tubular duct element, is retained on said element (1) with anti-rotation locking, in the unfinished state of assembly, in the region of said second connection end.
