<p>A clamping device (10) has a fixed jaw (12), a movable jaw (11) formed at one end of an operating lever (15) and two elastic units (30, 32) aligned and compressed along the operating lever (15). The elastic units, through the reaction of connecting rods (23), generate a force which rotates the operating lever upwards, causing the movable jaw (11) to clamp a cable (F) against the fixed jaw (12). An intermediate plate (35) is arranged between the two elastic units and has a portion (36) protruding outwardly beyond the elastic units (30, 32) in a direction transverse to the operating lever (15). The position of the protruding portion (36) provides a clear indication of the efficiency of the clamp.</p> |
