For easing the installation and the fitting to different actuating devices, the arm comprises means (30; 60) for longitudinally adjusting inside the first and/ or second segment the position of a relevant rotation axis (X) thereof. A segment, once the length thereof has been adjusted, can be cut.</p> |
