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 (122), at least one male and/or female attachment part (41) designed to engage selectively by attaching to at least one mating female and/or male attachment port (61) on the receiving device, the connector comprising a pressure-sensitive lock bolt (8, 83) in the fluid supply line, and being characterized in that in its first and second positions the lock bolt (8, 83) is so shaped as to lock or release the attachment part (41) via at least one intermediate locking part (5, 51) separate from the lock bolt, the intermediate locking part (5, 51) being selectively movable between a locked position and an unlocked position of the attachment part (41) or parts, and in that the lock bolt (8, 83) includes at least one member (83) such as a pin movable in relation to the intermediate locking part, the movable member (83) forming a retractable stop for the intermediate locking part (5, 51) depending on the pressure of the fluid in the supply line.
Raccord de remplissage et/ou de soutirage de fluide sous pression, notamment de gaz sous pression, destiné à être raccordé sélectivement à un dispositif receveur de fluide tel qu'un robinet d'un réservoir sous pression, ledit raccord comprenant un circuit (122) d'amenée de fluide, au moins un élément d'accrochage (41) mâle et/ou femelle prévu pour coopérer sélectivement en accrochage avec au moins un port d'accrochage (61) conjugué femelle et/ou mâle du dispositif receveur, le raccord comportant un verrou (8, 83) sensible à la pression dans le circuit d'amenée de fluide, caractérisé en ce que dans ses première et seconde positions le verrou (8,83) est conformé pour assurer le blocage ou le déblocage de l'élément d'accrochage (41) via au moins un élément de verrouillage intermédiaire (5, 51) distinct du verrou, l'élément de verrouillage intermédiaire (5,51) étant sélectivement déplaçable entre une position de verrouillage et une position de non verrouillage du au moins un élément d'accrochage (41), et en ce que le verrou (8,83) comprend au moins un organe (83) tel qu'un pion mobile, par rapport à l'élément de verrouillage intermédiaire, l'organe mobile (83) formant une butée escamotable pour l'élément de verrouillage intermédiaire (5,51) selon la pression du fluide dans le circuit d'amenée.
