In order to increase the utility of an arm clamp having a guide rail, on which a fixed transverse arm is seated, having a sliding arm which is displaceable on the guide rail and which can be tilted with the latter, and having a pressure application spindle with a pressure piece, which pressure application spindle is displaceably arranged on the sliding arm so that a compressive force can be exerted on a workpiece between transverse arm and sliding arm, a box-like attachment member is provided for the sliding arm, which provides a substantially flat abutment surface for a workpiece, and is so constructed that it can be pushed on the pressure piece of the sliding arm so that the attachment member is held on the sliding arm and a compressive force can be exerted by the attachment member on a workpiece via the pressure application spindle, and wherein the attachment member comprises at least two mutually spaced guide recesses via which it is displaceably mounted on the guide rail.
