Abstract: A device for retaining a boot on a gliding board and a gliding board equipped with such device. The device has a base and a rear support element articulated on the base along a substantially transverse journal axis of the device. The rear support element has two parts, an arch articulated on the base and a collar affixed to the arch, the collar having a greater rigidity than the arch, the arch cooperating with an arch/a bow of the base to limit a front-to-rear articulation movement of the rear support element with respect to the base.
