ABSTRACT:
A hypodermic syringe has a barrel, a piston with plunger located in the barrel cavity, an elongated body on the barrel forward end and a needle releasably secured to the body end. A sheath slidingly received onto the elongated body has arms with openings on their end portions which can be locked onto pins on the band exterior. The sheath also has shields which normally extend outwardly. A spring-loaded actuator sleeve is slidingly received on the sheath. When the plunger has emptied the barrel cavity, further movement releases the sheath arms from the pins and the spring-loaded actuator moves over the shields closing about the needle.
