<p>The device has a cylindrical shaft (8) connecting two guides of branches of a shackle, where the branches are arranged at an exterior of a bearing forming assembly (7). The cylindrical shaft is immobilized longitudinally in the bearing forming assembly traversed by the cylindrical shaft, by an elastic piece i.e. U-shaped spring (10), that is totally engaged in a housing (23) provided in the bearing forming assembly. The cylindrical shaft has a hollow relief (9) i.e. groove, that cooperates with the elastic piece.</p> |
