Claim 12:
13. The shield of claim 1, wherein the locking ring comprises:
a ring body having an outer face and an inner face, wherein the inner face faces the body cold end of the elongate body;
a channel having first and second hilt portions flanking a barrel portion, the channel extending entirely through the ring body from the outer face to the inner face, the hilt portions and the barrel portion dimensioned to permit the hilt and the barrel to pass respectively therethrough only while the syringe is in a first rotational orientation with respect to the ring body;
first and second hilt recesses in the ring body flanking the barrel portion of the channel, the hilt recesses extending only partway through the ring body from the inner face towards the outer face and dimensioned to receive respective portions of the hilt from the direction of the inner face of the ring body only while the syringe is in a second rotational orientation with respect to the ring body, the second rotational orientation being different than the first rotational orientation, wherein rotational movement of the syringe with respect to the locking ring is inhibited while the hilt is received within the first and second hilt recesses;
shelf structure associated with the hilt recesses for permitting rotation of the syringe between the first and second rotational orientations only while the hilt received within the channel is longitudinally level with the inner face of the ring body; and
resiliently deformable retention structure associated with the hilt recesses for selectively retaining the hilt within the hilt recesses, the retention structure moveable between a rest position in which the hilt recesses are partially obstructed and a release position in which the hilt recesses are substantially unobstructed, said retention structure biased to said rest position.
