<p>The arm (6) has a tubular body (9) placing a connection element (10), where the tubular body comprises an internal surface (24). The connection element comprises an external surface. The internal surface and the external surface are widened according to a slope (P). A screw (25) is engaged with a distal opening (20) that includes the connection element. The connection element includes a proximal opening (19) that is formed in a housing for receiving an end piece (8) of a workpiece (2). The proximal and distal openings are aligned with a proximal port (14) and another distal opening (15). An independent claim is also included for a method for assembling a tightening arm.</p> |
