The invention relates to a connecting device (1) comprising a base (10) which can be mounted on the vessel (2) and consisting of a sleeve (16) which forms an inner bore and a plunger (20) adapted to slide in the bore between a first released position relative to a cap of the vessel and a so-called transfer position, wherein the hollow needle (21) thereof passes through the cap. The needle (21) is provided with a non-circular external transverse section while the sleeve (16) is provided with a non-circular internal transverse section. The external section of the needle (21) and the internal section of the sleeve (16) are such that the needle can slide in the sleeve, without rotating therein. The edge (16d) of the sleeve opposite the cap is provided with stop means (16a, 16b) which can co-operate with complementary means (22d, 22e) which are disposed on the plunger (20) for locking the plunger in said transfer position.
Ce dispositif de connexion (1) comprend une embase (10) apte à être montée sur le récipient (2) et comportant un manchon (16) formant un alésage interne et un piston (20) apte à coulisser dans cet alésage, entre une première position dégagée par rapport à un bouchon du récipient et une position, dite de transfert, dans laquelle son aiguille (21) creuse traverse le bouchon. L'aiguille (21) est à section transversale externe non circulaire alors que le manchon (16) est à section transversale interne non circulaire, les sections externe de l'aiguille (21) et interne du manchon (16) étant telles qu'un coulissement de l'aiguille dans le manchon est possible, sans possibilité de rotation de l'aiguille dans le manchon. Le bord (16d) du manchon opposé au bouchon est pourvu de moyens (16a, 16b) d'arrêt aptes à coopérer avec des moyens complémentaires (22d, 22e) prévus sur le piston (20) pour le verrouillage du piston en position de transfert.
