The mounting (10) with a light barrier protective device for a machine has a guide unit (9) fixable on the machine tool (12) or its carrier and a guide element (19) movable in the working direction (A) of the tool and supporting the light barrier. A friction brake is provided to impede the displacement of the guide element, and a fixable stop element when in the stop position prevents a relative movement between the guide unit and guide element but allows it in the opposite direction.
