The device (1) can be joined to a spindle with its rear end (3) and hold a machining tool at the front with an elastic thin-walled sleeve (4) deforming under pressure and kept in position by a clamping ring (6). When the clamping ring (6) is rotated in relation to the main body (2) several elastic segments (11a, 11b, 11c, 11d) accommodated in the space (7) between the sleeve (4) and the clamping ring (6) are moved against the shaft of the tool located inside the central bore (5).
