ABSTRACT:
A single use syringe comprises a separable, reusable handle including a piston (6) and a support part (2, 3) for a sleeve (4) having an interlocking structure (5) through which the piston (6) extends. The syringe body (11) has a tubular end (16) with an interlocking structure cooperating with that of the sleeve (4) of the handle (1) and the shape of which is adapted to interlock with said sleeve, and a protecting shell (12) having a locking section (22) capable of covering the tubular end (16) and the sleeve (4) so that they are locked in their interlocking position, said protective shell (12) being adapted for sliding along the syringe body (11) between two extreme positions, i.e. a forward position where it totally covers the injection needle and a pulled back position where it frees it and covers the interlocked tubular end (16) and sleeve (4).
