Abstract
The present invention resides in an improvement to a syringe having a syringe housing and a plunger slidably positioned therein and extendable therefrom, and includes a novel locking member mounted on the plunger externally of the housing and angularly movable thereon between a first position in which the locking member can move longitudinally along the plunger and a second position in which the locking member becomes engaged with the plunger to hold the members together in fixed condition for movement in concert. The locking member is also shaped to move into abutment with the syringe housing where the plunger is moved to limit movement of the plunger when in its locked position.
