Abstract: A replaceable tip for a tool. A locking pin is disposed on a transverse opening in the end of the tool. A sleeve having a cammed surface formed interiorly is disposed over the end of the tool with the ends of the locking pin contacting the cammed surface. The replaceable tip has a locking keeper which engages the locking pin. Rotation of the sleeve in opposite directions locks or unlocks the locking keeper to the locking pin to allow retention or removal of the tip. In an alternate embodiment the sleeve has opposite spring fingers which contact the ends of the locking pin.
