The safety device includes a tubular body extending along a longitudinal axis. The tubular body is configured to receive the medical container, a needle cover movable relative to said body between a retracted position, and an extended position in which the needle cover distally extends from the retracted position in order to shield the injection needle after activation of the safety device, a release element configured to move the needle cover from the retracted to the extended position after activation of the safety device, and a retainer for maintaining the release element in a compressed condition when the needle cover is in the retracted position. The retainer is configured to transmit a user's activation force to the needle cover once the injection operation is completed. The needle cover includes a distal abutment surface, said distal abutment surface abutting against a proximal abutment surface of a bump protruding from the body in the retracted position of the needle cover. The bump has a first end and an opposite second end, and the proximal abutment surface of said bump has a ramp portion, said ramp portion having a decreasing slope towards the first end of said bump.

The distal abutment surface of the needle cover is located on a radial protrusion, and the radial protrusion has reinforcing means configured to reinforce a proximal side of this radial protrusion.

A medication administering device includes upper and lower housings. The lower housing supports a syringe having a needle. A needle guard is in sliding engagement with the lower housing and is proximally movable from a first position, wherein the needle guard conceals a tip of the needle, to a second position, wherein the needle guard exposes the tip of the needle. The upper housing is configured to receive a distally directed force and move relative to the lower housing from a pre-use position to a dispensed position in response to the manual force. When the upper housing is in the pre-use position and the needle guard is in the first position, the upper housing cannot move toward the dispensed position. Proximal movement of the needle guard from the first position to the second position frees the upper housing for movement to the dispensed position in response to the force.

The invention relates to a safe support device for a syringe, said support comprising a support sheath for the body of a syringe, and safety means which comprise an inner sheath suitable for sliding relative to said support sheath between a waiting retracted position, in which said inner sheath is substantially retracted inside said support sheath, and an active protection position, in which said inner sheath projects from said support sheath. The inner sheath has a free end portion formed by a flexible end-piece. The invention also relates to an assembly comprising such a safe support device and a syringe having a body, a piston and a needle disposed at one end of said body.
