The present invention relates to a pivot permitting the use of a fixed gymnastics bar without having to use holding cables. The spring system (8) compressed between the pivot (5) and the cover (1) makes it possible, on the one hand, to have the necessary bearing (support) on holding the bar (7) between the pivot and the hollow spherical portion (6) integral with the casing (3) and, on the other hand, being slipped (sleeved) at their ends over equidistant guiding fingers offset by 120@, make it possible to block the bar on its longitudinal shaft in order to prevent rotation thereof. <IMAGE>
