Abstract: A safety connector has a needle, and includes a tubular protective sleeve with a distal section, having a movable wall portion arranged in the peripheral wall thereof. The movable wall portion is selectively movable between a retracted position and a protection position. In the retracted position, the movable wall portion is aligned with the peripheral wall of the proximal section of the tubular protective sleeve. In the protection position, the movable wall portion projects into the inner space of the tubular protective sleeve.

Abstract: Sampling or transfusion device with protection means including a protective tube that slides longitudinally along the axis in an annular passage between the external body and the central body and has a proximal holding end for moving it selectively between a proximal retracted position in which the needle is not covered by the protective tube or not much covered thereby so that the latter can be used to draw a sample or to administer a transfusion and a distal protection position in which the protective tube covers the needle over the whole of its length.

Abstract: A connector according to the invention comprises a hollow needle fastened to a body. A first tubular receptacle provided with a first foil surrounds a first end section of the needle. A second tubular receptacle provided with a second foil surrounds a second end section of the needle. The tubular receptacles are able to slide on the body. The holding sleeve moves the body toward the first foil over a first piercing stroke to pierce it, and then moves the second foil toward the body over a second piercing stroke to pierce it. In this way there may be obtained simultaneous piercing of the foils and foils or stoppers of containers such as flasks or sachets pressed against the foils, to provide a connection under optimum conditions of sterility.

Abstract: A safety needle connector according to the invention comprises a hollow needle through which fluid may pass fastened to a needle support sleeve itself connected to a fluid tube. The needle support sleeve may be connected by clipping it axially into a receiving structure of a protective cylinder that surrounds a projecting needle portion. The receiving structure comprises receiving cylinders in which the needle support sleeve is engaged and comprising locking tongues that cooperate with a bearing flange to allow penetration of the needle support sleeve and prevent its withdrawal. A closure sleeve is engaged around the projecting needle portion to form a sealed connection in the needle passage.
