Abstract

A valve for pressurized fluid housing a fluid circuit having an upstream end and a downstream end and a valve for controlling the flow rate in the circuit that is controlled by a movable actuating member in order to control the opening or the closing, the valve having a lower end provided with movable coupling member(s) intended to cooperate with one or more complementary coupling members on a gas source or a circuit, the valve further comprising a member for locking the coupling member(s) that is mounted movably on the body of the valve between a first position not blocking the movement of the coupling member(s) and a second position blocking the movement of the coupling member(s).
