ABSTRACT:
A protective sleeve for the needle of a hypodermic syringe includes a formed resilient plastic body. The body is split longitudinally to form slightly greater than a semicylinder. The body is snapped onto the barrel of a hypodermic needle before or after the needle is used. It may be slid longitudinally over the needle to protect against accidental puncture by the needle after the needle is used and locks into this position.
