Abstract
A shield for a hypodermic needle assembly includes a hollow plastic sleeve with an elongated main portion adapted to normally enclose the main portion of a needle, a slidable outer end portion which normally extends beyond the tip end of the needle, the elongated main portion of the hollow sleeve responding to an axial force on the outer end portion for expanding radially outwardly to retract the end portion of the sleeve and expose the needle tip end, a spaced pair of circumferential flanges formed on the elongated main portion of the sleeve, and a flexible collar encircling the sleeve and slidable over one of the flanges so as to occupy a position between the flanges and thereby prevent subsequent expansion of the main portion of the sleeve.
