An Insert (4) for a pipe-fitting system comprising a fitting (2) and a pipe (3) is provided. The insert (4) is adapted to be inserted into the fitting (2) and is adapted to receive the pipe (3) an outer diameter of which substantially corresponds to the inner diameter of the inner circumferential face of the insert (4). The inner circumferential face is provided with a sealing portion (4a, 4a1, 4a2) adapted to seal between the insert (4) and the pipe (3) and a holding portion (4d) for holding the pipe (3), being different from the sealing portion (4a, 4a1, 4a2). An outer circumferential face of the insert (4) is provided with at least one circumferential groove (5) for engaging with a deformed portion of the fitting (2).
L'invention porte sur un insert (4) pour un système tuyau-raccord comprenant un raccord (2) et un tuyau (3). L'insert (4) est apte à être introduit dans le raccord (2) et apte à recevoir le tuyau (3) dont un diamètre externe correspond sensiblement au diamètre interne de la face circonférentielle interne de l'insert (4). La face circonférentielle interne comporte une partie d'étanchéité (4a, 4a1, 4a2) apte à sceller de façon étanche l'espace entre l'insert (4) et le tuyau (3), et une partie de maintien (4d) pour maintenir le tuyau (3), qui est différente de la partie d'étanchéité (4a, 4a1, 4a2). Une face circonférentielle externe de l'insert (4) comporte au moins une rainure circonférentielle (5) destinée à s'engager avec une partie déformée du raccord (2).
