The chuck has a rigid base body (2), a central holder and a tapered ring (8) to fix an article by elastically deforming a clamp sleeve (7). An annular groove (6) in the base body surrounds the holder and is open at the end face of the base body. The tapered ring has a ring body (8a) and several spaced clamp tongues (8b), which have a wedge cross-section towards their free ends and are pressed into the groove by deforming the clamp sleeve.
