A coupling assembly includes a first coupling member (20) extending along an axis (A-A) from a leading end (21) to a trailing end (22) and having an exterior that includes a first locking surface (28). A second coupling member (30) extends from a receiving end (50) to a remote end (51) and includes a receiving portion sized to receive the first coupling member (20). The second coupling member (30) also includes a second locking surface (55). A latching sleeve (33) is positioned between the first and second coupling members (20, 30) and includes a bead (39). The latching sleeve (33) is sized such that as the first coupling member (20) is inserted into the second coupling member (30), the latching sleeve (33) is compressed as the bead (39) engages the second coupling member (30) and then expands as it moves over the second locking surface (55) to become engaged between the first locking surface (28) on the first coupling member (20) and the second locking surface (55) on the second coupling member (30).

L'invention concerne un ensemble couplage qui comprend un premier élément de couplage (20) se déployant le long de l'axe A-A, d'une extrémité avant (21) à une extrémité arrière (22), et qui comporte sur sa partie extérieure une première surface de blocage (28). Un second élément de couplage (30), qui se déploie d'une extrémité réceptrice (50) à une extrémité distale (51), comprend une partie réceptrice conçue pour recevoir le premier élément de couplage (20). Le second élément de couplage (30) comprend aussi une seconde surface de blocage (55). Un manchon de verrouillage (33), placé entre les premier et second éléments de blocage (20, 30), comprend un collet (39). Le manchon de verrouillage (33) est conçu de sorte que lors de l'insertion du premier élément de couplage (20) dans le second élément de couplage (30), le manchon de verrouillage (33), comprimé au moment où le collet (39) entre en contact avec le second élément de couplage (30), se déploie ensuite à mesure qu'il se déplace sur la seconde surface de blocage (55) jusqu'à ce qu'il soit immobilisé entre la première surface de blocage (28) du premier élément de couplage (20) et la seconde surface de blocage (55) du second élément de couplage (30).
