A clamp for clamping a workpiece comprises a base member a clamping member mounted on the base member for linear movement relative thereto and a drive member mounted on the base member for rotary movement relative thereto. First and second cam elements comprising a face cam are provided on the drive member and the base member, at least one of the cam elements including at least two portions of different pitch. The arrangement is such that rotation of the drive member relative to the base member causes linear movement of the clamping member relative to the base member.
