Abstract: A device for retaining a boot on a gliding board. The device includes in particular a dorsal support element and a base, the dorsal support element being journalled on the base along a substantially transverse Y-Y' axis of the device, wherein at least one control device generates a journal movement of the dorsal support element with respect to the base along the Y-Y' axis, from an opening position toward a closing position in a rear-to-front direction, when the sole of the boot is displaced toward the board during affixation of the boot, wherein an elastic element biases the dorsal support element along the Y-Y' axis in a front-to-rear direction, wherein a stop limits the movement of the dorsal support element in the front-to-rear direction, and wherein the dorsal support element has a scallop at the level of the heel of the boot.
