At least one operating lever (14) is mounted on the body (10) and the, or each, lever is operable to move a jaw (12) radially. The, or each, lever is also movable axially with respect to the chuck body (10), to disengage from the associated jaw (12), enabling the associated jaw (12) to be removed simply and quickly from the chuck body (10) by movement in the radial direction.
