Abstract
A plastic needle guard is mounted on a hub in which a needle is secured. In order to cover the end of the needle, the needle guard is slid manually off the hub and over the end of the needle to position the needle end within the guard. A washer that is loosely mounted within the guard and through which the needle passes drops off the end of the needle to block any return movement of the needle out of the guard. Other embodiments use lock-type washers to prevent a return movement of the needle.
