Abstract
Two hoses in the cooling circuit of a vehicle engine are secured to respective tubular members for coupling to respective tubular endpieces of a heat exchanger, e.g. a radiator or a heater. The tubular members have respective through openings extending transversely to their longitudinal axes, and they are associated with a plate disposed in the vicinity of said openings. Each endpiece has a catch groove associated with a respective ramp. In the coupled position, the grooves coincide the openings. Respective branches of a U-shaped spring clip are received in the openings and engage in the grooves when the endpieces are pushed into the tubular members, thereby snap-fastening the coupling device together. The tips of the branches have respective lugs that co-operate with tabs of the plate. The tab are shaped to cam the lugs during snap-fastening in such a manner as to ensure that, providing snap-fastening has taken place properly, the entire spring clip is shifted to a position that is visibly distinct for ease of checking and that is also locked such that uncoupling can be performed only by means of a special tool for splaying the branches apart.
