A connector device (10) for fluidly connecting two septum sealed containers (60, 64) comprises a first member (20) and a second member (40) that are slidably displaceable in regard to each other along an axis (12) between a first and a second position. The first member (20) comprises a hollow transfer needle (24) with two pointed ends (25, 25), arranged parallel to said axis in such a way that a septum (62) of a first one (60) of the containers is penetrated by one end (25) of the needle when said first container is introduced into a receptacle (21) of the first member. The second member comprises means (42) for releasably coupling to the second one (64) of the two containers. The other end (25) of the needle does not come into contact with a septum (66) of the second container (64) coupled to the second member when the members are in the first position. Said other needle end (25) penetrates the septum of the second container when the members are in the second position thereby establishing a fluid connection between the two containers. The first member (20) comprises means (22) for releasably coupling to the second container (64) coupled to the second member. The first member (20) comprises means (22) for releasably coupling to the second container (64) coupled to the second member (40), wherein said coupling means (22) of the first member can couple to said second container when the two members are in the second position, and cannot couple to said second container when the two members are in the first position.Linvention concerne un dispositif (10) connecteur destiné à relier de manière fluidique deux contenants (60, 64) fermés de manière étanche par un septum, qui comporte un premier élément (20) et un second élément (40) qui se déplacent lun par rapport à lautre en coulissant le long dun axe (12) entre une première et une seconde position. Selon linvention, le premier élément (20) comporte une aiguille (24) de transfert creuse présentant deux extrémités (25, 25)
