Abstract
A chucking device for a dental tool in a dental handpiece or angle head includes a clamping sleeve with resilient tongues. The resilient tongues of the clamping sleeve are arranged at a distance from each of the two ends of the clamping sleeve. On the side on which an actuating member for the resilient tongues is provided, the internal width of the clamping sleeve is greater than the external diameter of the tools to be used. The actuating member for the resilient tongues is an essentially tubular member whose external diameter corresponds to the internal width of the clamping sleeve and whose internal diameter corresponds to the external diameter of the tools to be used.
