The protective shield for a hypodermic syringe includes a tubular body which overlies the needle of the syringe when the shield is in the forward position. The protective shield has an opening therein to permit exposure of the needle when the shield is in the retracted position. A detent engages the syringe and the shield to limit relative motion therebetween and to releasably lock the shield in its end positions.
