The invention relates to a braking disc comprising a braking band and a support bell. The band comprises first connecting means and the bell comprises second connecting means adapted to face the first connecting means. The disc further comprises coupling means, each of which is slidingly associated to one of either said first or said second connecting means and is adapted to alternatively take either a fastening position or a release position. When the coupling means are in said fastening position mutually fasten the band and the bell in the axial direction. On the other hand, when the coupling means are in said release position, they allow a mutual movement between the band and the bell in the axial direction.
