A gripper includes a body, at least two jaws (11, 11'), which can move linearly on the body in opposite directions and at least one fluid-type piston (12, 12') that is arranged in the body and is intended to control the movements of the jaws. The jaws are supported and guided on said body with the interposition of at least one cylindrical bolt (26, 26') arranged in facing semicylindrical slots (27, 27') provided on one side of the jaws and in an adjacent part of the body.
