Abstract

The invention relates to a single-use safe injection device comprising a syringe body (1), a protective sleeve (8) and locking means (15, 16) for keeping the syringe body in an injection position. According to the invention, the protective sleeve (8) comprises a rear section (17) in which a tubular slider (25) for actuating the push‑button (6) of the stem (5) of the syringe piston (4) is slidably mounted, the said slider comprising axial stop means (28, 29) designed, on the one hand, to allow the push‑button (6) to be actuated over the entire travel of the piston (4), and on the other hand to retract radially, when the slider (25) is in a forward position obtained after the locking means (15, 16) have switched into an unlocked state, so as to allow the syringe body (1) to slide into a position in which it is retracted inside the protected sleeve (8).
