Pressurized fluid filling and/or extracting connector, particularly for a pressurized gas, said connector being designed to be selectively connected to a fluid receiving device such as a tap of a pressurized tank, said connector comprising a fluid supply line, at least one male and/or female attachment part designed to engage selectively by attaching to at least one mating female and/or male attachment port on the receiving device, the connector comprising a pressure-sensitive lock bolt in the fluid supply line, and being characterized in that in its first and second positions the lock bolt is so shaped as to lock or release the attachment part via at least one intermediate locking part separate from the lock bolt, the intermediate locking part; being selectively movable between a locked position and an unlocked position of the attachment part or parts, and in that the lock bolt includes at least one member such as a pin movable in relation to the intermediate locking part, the movable member forming a retractable stop for the intermediate locking part depending on the pressure of the fluid in the supply line.
