<p>The assembly has a tightening device (15) comprising a driving lever (43) that is articulated to a base. A driving end of the lever drives a band (14) along a direction. Straight lines (d1, d2) for a tooth (29) of teeth of the band are tangent to a meshing surface (30) of the tooth and parallel to a surface of the band to form angles (alpha1, alpha2) less than 90 degrees with a longitudinal direction (L14) of the band. The driving end of the lever cooperates with the succession of the teeth of the band. A retaining zone of a pawl cooperates with the succession of teeth of the band.</p> |
