The clamping device for clamping work pieces comprises a box-shaped body, and an angularly movable clamping arm, operatively connected to an electric control actuator by a toggle-lever mechanism and an axially extensible thrust member. The toggle-lever mechanism comprises a connecting link having first and second link sections hinged on opposite sides of a crank member of the clamping arm, and to a screw and nut mechanism of the thrust member. The screw slides in an axial through bore which extends along the thrust member and through a hole in a hinge pin which connects the thrust member to the sections of the connecting link.
