ABSTRACT:
A locking protective cover for a needle or cannula of a hypodermic syringe, blood collector or other device includes a retractable cap member connected to the base of the needle by a resilient support that biases the cap member to a cover position around the needle tip. The cap member provides a needle channel for axial passage of the needle and a tip storage bore laterally connected to a needle channel through a one way locking path that permits transfer of the needle to the storage bore without removal of the tip from the cap member.
