Clamp for fastening sheets, which is essentially characterized by the fact that it consists of a base piece that extends at one end in one of the arms of the clamp, while on said base the second arm is articulated, subjected to the action of a spring that tends to keep it folded over the first, with both arms being provided on their internal working faces of respective corresponding jaws, at the same time that the base piece is subsequently articulated with a freely rotating lever, with a grooved upper working surface and which acts by tilting the lever against the trailing edge of the movable arm of the clamps, so that it forces it to close to the maximum against the opposite arm and holds it in that position.
