Abstract
A hand manipulated implement including an implement head, a handle and a connector rigidly connecting the handle to the implement head. The connector includes a plug which is inserted into the handle and which includes an exposed end for inserting into a collet base defined on the implement head. The connector plug and collet base each include an aperture wherein the apertures of the plug and base are aligned by ribs cooperating with grooves and slots at the lower ends of the plug and collet base. A clip is inserted through the aligned apertures to thereby hold the handle against longitudinal movement relative to the collet base. In addition, a collet is formed at an upper end of the collet base for frictionally engaging the handle and thereby further limiting movement of the handle relative to the implement head.
