A safety device for a vehicle door of the type actuated by a turnable shaft driven by a piston cylinder unit having a piston rod connected by a hinge bolt to a lever arm fixedly mounted on the turnable shaft. The safety device comprises a carrier coupled to the lever arm and slidably receiving the piston rod, a switch element on the carrier and a control element on the piston rod. When the door encounters an obstacle, the control element is brought into contact with the switch element to reverse the direction of movement of the door.
