Abstract:
1. A tubular endpiece for a self-closing coupling device, the endpiece ( 2 ) including one end ( 3 ) for coupling to a member and being provided on the outside with means ( 5 ) for preventing it from moving axially in a housing of the coupling device, and being fitted internally with a valve slide ( 33 ) mounted to slide relative to a valve seat ( 37 ) between a closed position and an open position, and a spring ( 40 ) interposed between an internal shoulder ( 41 ) of the endpiece and the valve slide in order to urge the valve slide into its closed position against the valve seat, the valve seat being formed by an internal shoulder ( 41 ) of a sleeve ( 23 ) fitted in the endpiece and arranged to form a guide sleeve for the valve slide ( 33 ) which is extended downstream by a perforated tubular tail ( 38 ) slidably received in the sleeve ( 33 ).
