End piece (2) for a corrugated hose (6), comprising: a bus-hing (8) having a front region (12) and a rear region (20) opposite of a longitudinal direction (L), said rear region being located inside the corrugated hose (6) in the mounted state of the bushing (8). The front region (12) of the bushing (8) consists of a collar (14), which forms a groove (16) along the circumference of the bushing (8) for receiving the free end (4) of the corrugated hose (6). The rear region (20) of the bushing (8) consists of a plurality of flexible tongues (22), which have a relief direction that is oriented perpendicular to the longitudinal direction (L) of the bushing (8) and directed toward the outer chamber (AN) of the bushing (8). At least a portion of the flexible tongues (22) comprises a radially projecting detent protrusion (26) for implementing an engagement active in the longitudinal direction (L) of the bushing (8). A retaining sleeve (10), which can be received by the bushing (8) with precise fit and, in the mounted state of the end piece (2), extends in an inner chamber (IN) enclosed by the bushing (8), li-mits the radial play of the flexible tongue (22).

L'invention concerne une pièce d'extrémité (2) pour un tuyau annelé (6), comprenant : un manchon (8) présentant une zone avant (12) et une zone arrière (20) opposée, en direction longitudinale (L), qui, en l'état monté du manchon (8), se trouve à l'intérieur du tuyau annelé (6). La zone avant (12) du manchon (8), comprend un col (14) qui forme une rainure (16) s'étendant le long de la périphérie du manchon (8), destinée à recevoir l'extrémité libre (4) du tuyau annelé (6). La zone arrière (20) du manchon (8) comprend une pluralité de languettes élastiques (22) qui présentent une direction de décharge, dirigée en direction de l'espace extérieur (AN) du manchon (8), orientée perpendiculairement à la direction longitudinale du manchon (8). Au moins une partie des languettes élastiques (22) présente une saillie d'encliquetage (26) s'étendant radialement, en vue de réaliser une prise efficace en direction longitudinale (L) du manchon (8). Un manchon de blocage (10), reçu en ajustage serré, par le manchon (8), s'étendant, à l'état monté de la pièce d'extrémité (2) dans un espace intérieur (IN) entouré par le manchon (8), limite le jeu radial des languettes élastiques (22).
