Abstract: A clamping device for clamping a rodlike member to a housing, particularly a dental tool to a handpiece, includes a tapered sleeve and a tapered collet received within the tapered sleeve, both having open ends for receiving the rodlike member. The inner diameter of the sleeve and outer diameter of the collet decrease from their open ends to their opposite ends. The tapered collet is formed with an axial slit starting from its open end and extending along a part of its length towards its closed end, permitting the collet to contract in diameter in order to firmly clamp the rodlike member. A depressable button is engageable with the closed end of the tapered collet to move the collet outwardly of the tapered sleeve, thereby to expand the tapered collet and to permit removal or insertion of the rodlike member.
