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).
