Abstract
A syringe mechanism includes a pair of sub-assemblies one of which contains a pair of threaded connector elements. One such connector element slidably surrounds a plunger rod while the other is adapted to surround a tubular barrel of the other sub-assembly. Upon engagement and tightening of the threaded elements, a resilient sleeve disposed intermediate the barrel and its surrounding connector element, is axially fore-shortened or compressed and inwardly displaced to firmly interlock the two sub-assemblies with the forward end of the plunger rod disposed within the barrel.
