The pincers have a female jaw (2), a male jaw (3) and a key (4). The jaws are each apertured and the key slides across the apertures. The pincers have supports allowing tilting of the key to an extended position. The pincers have a profiled base (6) having a groove (g) on its inner face. The tilting or rotation of the key occurs around an axis (65) perpendicular to a plane (67) parallel to the sliding axis (9) between the two jaws.
