Abstract
A sleeve for coupling a tool to a handle includes a collar, a shank and a pair of resilient clips. The collar defines proximal and distal ends, and includes an exterior surface which converges from the proximal end toward the distal end. In addition, the collar includes a central bore for receiving a shaft of the tool. In an especially preferred form, the central bore is so dimensioned as to fit closely around a shaft of the tool. In addition, the exterior surface of the collar meets an interior surface of the central bore at a right or acute angle. Then, the portion of the exterior surface of the collar near the juncture with the interior surface of the central bore acts as a knife edge to scrape deposits such as caked mud from the shaft of the tool as the shaft is inserted into the sleeve. The sleeve is preferably formed from a weather-resistant plastic and the proximal end of the collar preferably has an outer diameter greater than an outer diameter of an adjacent portion of the shank so as to provide some protection to an end of the handle against corrosion due to exposure to the elements.
