<p>Quick coupling for coupling one or a set of tubular members to one or more end-fittings, by snap-fitting, particularly for joining water pipes (6, 7) in the cooling circuit of a motor vehicle engine to the inlet and outlet end-fittings (1, 2) of a heat exchanger or unit heater of the said vehicle. It comprises at least one elastic pin (20) each branch (18, 19) of which, housed in an opening of the tubular members, terminates at its free end in a turned back part (21, 22) pointing substantially perpendicularly to the said branch, the turned back parts (21, 22) interacting with tabs of a mounting plate (31) which are shaped so that they guide the said turned back parts when ramps (53) associated with the end-fittings (1) elastically move the said branches (18, 19) of the pin apart when passing from the unjoined state to the joined state. <IMAGE></p> |
