Abstract
The needle end of the barrel of a pre-filled syringe is sealed by a stopper which is displaceable into the shaft of a needle holder. The stopper is displaced, to release injection fluid, by operation of the syringe plunger. One or more slots in the walls of the needle holder shaft and the rear face of the needle holder neck conduct fluid around the displaced stopper. The stopper substantially fills the shaft of the needle holder but does not cover the ends of the slots which adjoin the barrel.
