摘要

A device for fitting a needle on a cartridge syringe (1) has a tubular body (20) engaged so as to slide axially on the proximal end of the body of the syringe (1), and locked into place by attachment teeth (22) co-operating with radial studs (11). By pivoting (56) a resilient lever (23), the tubular body (20) carrying the needle (6) is unlocked, the tubular body (20) and needle (6) assembly being thereafter ejected and introduced in a safety container (51).
