A coupling assembly includes a fitting having a wall presenting an inner surface, surrounding a lumen, and an outer surface, opposing the inner surface. A barb extends radially away from the outer surface of the wall to a peak. A seal circumferentially surrounds the outer surface of the wall and is spaced from the peak of the barb. A hose presents an initial outer diameter. The hose extends over each of the seal and the barb such that the hose is deformed at the barb to present a displaced outer diameter that is greater than the initial outer diameter of the hose. A cage is spaced at least a distance from the peak of the barb and radially compresses the exterior surface of the hose and the seal to form an interference fit between each of the hose, the barb, and the cage.

Un ensemble de couplage comprend un raccord ayant une paroi présentant une surface interne, entourant une lumière, et une surface externe, opposée à la surface interne. Une arête s'étend radialement à distance de la surface extérieure de la paroi vers un pic. Un joint entoure circonférentiellement la surface extérieure de la paroi et est espacé du pic de l'arête. Un tuyau présente un diamètre extérieur initial. Le tuyau s'étend sur le joint et l'arête, de sorte que le tuyau soit déformé au niveau de l'arête pour présenter un diamètre extérieur déplacé qui soit supérieur au diamètre extérieur initial du tuyau. Une cage est espacée sur au moins une distance du pic de l'arête et comprime radialement la surface extérieure du tuyau et du joint pour former un ajustement par interférence entre le tuyau, l'arête et la cage.
