A clamping device has an actuator that moves linearly and is actuated by a drive. A pivoting clamping element is operatively connected, via a toggle lever mechanism, with the actuator. The toggle lever mechanism includes a drive-side adapter and a hand lever-side adapter. The drive side adapter and hand lever side adapter can be adjusted relative to one another to define an opening angle of the clamping element. One of the adapters has a profiled bar extending in a direction of actuation. The other adapter has an insertion region to accommodate the bar. A fixing element is provided in one of the adaptors to define the location of the adapters relative to one another. The fixing element can be clamped against the profiled bar and also against an insertion region.
