<p>The handlebar (1) has a tightening unit comprising hemicylindrical clamping units (10, 11) extending transversely in a housing (12) presenting an opening (12') directed towards bottom for allowing introduction of a pivot tube. Upper and lower ends of the clamping units are equipped with receiving recesses (13, 14) adapted to periphery of the pivot tube. The housing comprises a partially cylindrical wall (15) cooperating with one of the clamping units to define an assembly of articulation units.</p> |
