Lorsque le tuyau (H) est inséré, le diamètre interne d'une partie entrée (3a) d'un manchon expansible et contractable (3) opposé à une partie à diamètre décroissant (1a2) est défini pour être supérieur au diamètre externe du tuyau (H) qui est inséré le long de la partie à diamètre décroissant (1a2) d'une partie bombée (1a), l'extrémité avant du tuyau (H) est introduite en douceur entre le manchon expansible et contractable (3) et la partie à diamètre décroissant (1a2) sans amener l'extrémité avant du tuyau à buter contre la partie entrée (3a) du manchon expansible et contractable (3) et peut être insérée à un emplacement prédéterminé. Par la suite, lorsqu'il est comprimé par une partie surface de compression (2b) suivant le mouvement axial d'un outil de serrage (2), le diamètre interne de la partie entrée (3a) du manchon expansible et contractable (3) est défini pour être inférieure au diamètre externe du tuyau (H) inséré le long de la partie à diamètre décroissant (1a2) de la partie bombée (1a), le tuyau (H) étant maintenu entre la partie entrée (3a) du manchon expansible et contractable (3) et la partie à diamètre décroissant (1a2) d'un mamelon (1).
