This connection device (1) comprises a base (10) adapted to be mounted on the recipient (2) and comprising a sleeve (16) forming an inner bore, and a plunger (20) adapted to slide in said bore, between a first position disengaged with respect to said stopper of the recipient and a so-called position of transfer, in which its hollow needle (21) traverses the stopper. The needle (21) presents a non-circular outer cross-section, while the sleeve (16) presents a likewise noncircular inner cross-section, the outer section of the needle (21) and inner section of the sleeve (16) being such that the needle can slide in the sleeve, without the possibility of rotation of the needle in the sleeve. The edge (16a) of the sleeve opposite said stopper is provided with stop means (16a, 16b) adapted to cooperate with complementary means (22d, 22e) provided on the plunger (20) to lock it in position of transfer. |
