Abstract
A plastic pre-filled syringe which includes an open ended barrel sealed at one end by a moveable stopper and sealed at the other end by a closure frangibly connected to the syringe. The syringe also includes an overcap which can be moved so to engage with the closure whereby removal of the overcap will cause the closure to be separated from the rest of the syringe and reveal the contents for injection.

A plastic pre-filled syringe which includes:
- (a) an open ended barrel sealed at one end by a moveable stopper and sealed at the other end by a closure frangibly connected to the syringe;
- and
- (b) an overcap which includes closure retention means able to hold and retain at least the end of the closure;
- wherein said overcap is moveable from a first position, from which removal of said overcap will not cause the frangible connection of the closure to the syringe to be broken, to a second position in which the closure is held and retained by the closure retention means and from which removal of the overcap will cause the closure to be separated from the rest of the syringe so to reveal the contents for injection.
