Abstract
In a hypodermic syringe having a sliding cap to prevent accidental pricking of the user, a needle hub assembly is provided with radial flaps having arcuate bands which extend in both circumferential directions from the ends of the radial flaps. The arcuate bands make a sliding engagement with the interior surface of the cap. An interference bead is positioned on the interior surface of the cap so that when the arcuate bands are positioned between the interference bead and the mouth of the cap and in engagement with the interference bead, the proximal end of the needle hub assembly will be spaced from the mouth of the cap within the cap.
