The device for bidirectional transfer between a vial (14) and a carpule (12) comprises: a body (16) having means (18) for fastening on the vial (14); a hollow needle (24); a moving element (20) which is displaceable with respect to the body (16) along the axis of the needle (24), said moving element (20) having means for constraining the reservoir (25) of the carpule to move axially in the direction of the axis of the needle (24); and a distance sleeve (22) interposed between the body (16) and the puncturable piston (27) of the carpule, said distance sleeve (22) forming a limit stop for the puncturable piston (27) with respect to the body (16). The hollow needle (24) is rigidly joined to the body (16) and is axially fixed with respect to the body (16).
