Abstract: There is disclosed a protective enclosure for hypodermic syringe needle formed by a tubular sleeve sized for friction fitting engagement over the barrel portion of the syringe, a needle guard portion at the opposed end thereof. The needle guard including a central needle channel traversing the same, and the needle guard being spaced from the tubular sleeve a distance such that the tip end of the syringe needle lies within the confines of the central needle channel in a normal resting position thereof. The sleeve and needle guard are connected by two pair of pivotally movable arms which operate to permit the needle to pass through the central channel during injection, and rest in a needle pocket when injection has been completed.
