A vehicle coolant system (10) includes a service valve (26) through which coolant is added to or removed from the coolant system (10). The service valve (26) includes a first and second port (32, 34), and a rubber hose (24, 28) is fitted over both the first and second ports (32, 34). A sealing ring (42) having an integrated barbed attachment feature (44) is overmolded on the joint of the rubber hoses (24, 28) and the respective ports (32, 34). The integrated barbed attachment feature (44) is inserted into an aperture (62) in a structural element (30) of the vehicle. As the integrated barbed attachment feature (44) passes through the aperture (62), the plurality of barbs (54) flex. After passing through the aperture (62), the plurality of barbs (54) return to the original position, securing the service valve (26) to the structural element (30). Alternately, the sealing ring (142) includes an integrated projection (170) having an aperture (162), and the structural element (130) includes a barbed attachment feature (144) including a plurality of barbs (154).

L'invention concerne un système (10) de refroidissement d'un véhicule équipé d'une soupape (26) d'alimentation automatique à travers laquelle un liquide de refroidissement est ajouté ou retiré du système (10) de refroidissement. La soupape (26) d'alimentation automatique comprend un premier et un second orifice (32, 34), et un tuyau (24, 28) en caoutchouc est fixé sur le premier et le second orifice (32, 34). Un anneau (42) d'étanchéité présentant un élément de fixation cannelé intégré (44) est surmoulé sur l'articulation des tuyaux (24, 28) en caoutchouc et des ports correspondants (32, 34). L'élément de fixation cannelé intégré (44) est inséré dans une ouverture (62) d'un élément structurel (30) du véhicule. Lorsque l'élément de fixation cannelé intégré (44) passe par l'ouverture (62), la pluralité de cannelures (54) fléchissent. Après leur passage par l'ouverture (62), la pluralité de cannelures (54) retournent à leur position initiale, fixant la soupape (26) d'alimentation automatique à l'élément structurel (30). En variante, l'anneau (142) d'étanchéité comprend une saillie intégrée (170) avec une ouverture (162), et l'élément structurel (130) est pourvu d'un élément de fixation cannelé (144) comprenant une pluralité de cannelures (154).
