Claim 0:
1. A valve for pressurized fluid, with or without integrated pressure reducer, comprising:
a valve body housing a fluid circuit having an upstream end configured to be placed in communication with a pressurized fluid reserve and a downstream end configured to be placed in communication with a user apparatus,
the circuit comprising a valve for controlling the flow rate in the circuit,
the valve being controlled by a movable actuating member in order to control the opening or the closing thereof,, the valve comprising:
a lower mounting end provided with movable coupling member(s) configured to cooperate with one or more complementary coupling members to form a quick connection system between the valve and a gas source or a circuit,
a locking member for locking the coupling member(s) that is mounted movably on the valve body between a first position and a second position with respect to the valve body, with, in the first position, the locking member not blocking the movement of the coupling member(s) and, in the second position, the locking member blocking the movement of the coupling member(s),
the locking member comprising a first end configured to cooperate with the coupling member(s) for the blocking thereof when said locking member is in the second position, and a second gripping end configured to manually move the locking member into the first position,

at an upper end, a fixed head, wherein the gripping end is situated in a housing of the head and is movable in the head between a top position at least partially retracted into the head when the locking member is in the first position, and a bottom position projecting at least partially beneath the head when the locking member is in the second position.
