An actuating device is reciprocably mounted in the supporting body and between the jaws and is operably connected to the end portions of the jaws to move them toward and away from each other upon reciprocal movement of the actuating device. The body is in the form of a cylinder and a fluid operated, doubleacting piston is reciprocably received therein and connected to the actuating device for the reciprocation thereof. The jaws extend longitudinally of the cylinder on diametrically opposite sides thereof and the actuating device extends axially of the piston.
