Abstract

An injection device comprises a needle (A) and a base (E), and a means for disabling the needle after a single use. The disabling means comprises a flexible elastic sheath (10; 500) which at least partially surrounds the needle (A) and is elastically compressible along the length thereof, and a rigid shield (20; 200) that can be selectively retained by the sheath in a delivery position in which the shield bears laterally against the needle and in which the tip of the needle can be disengaged from said shield (20; 200), characterized in that a stress applied to the sheath during the injection causes the shield to leave its delivery position and move axially in the direction of the tip of the needle, such that it flips over spontaneously and covers said tip.
