ABSTRACT:
A shieldable syringe assembly includes a syringe barrel having opposed proximal and distal ends and an annular groove extending inwardly near said distal end. A locking collar is mounted on said distal end of said syringe barrel and includes a plurality of barbs engaged in the groove. Outer portions of the locking collar aligned with the barbs define a collet that is inwardly deformable. A rigid safety shield is telescoped over the locking collar and the syringe barrel. The safety shield can be slid from a proximal position to a distal position. Interior portions of the safety shield are configured to lockingly engage the collet when the safety shield is in the distal position. The collet engaging portions of the safety shield deform the collet inwardly into tight gripping engagement in the groove on the syringe barrel for preventing separation of the safety shield and the locking collar from the syringe barrel.
