Abstract

A needle tip protecting device is provided for hypodermic needles, catheters and the like. The device is small enough to be stored at the base of the needle prior to and during use. After use it may be slid to cover the needle tip where it automatically self-attaches and becomes non-removable. Embodiments of mechanisms which achieve this effect by means of a tapered cavity, collet or angled jamming surface are described.
