Abstract: A toepiece of a binding to secure a boot to a gliding board includes two rigid jaws pivotable about respective horizontal axes oriented in a longitudinal direction. A releasing system for automatically releasing the boot by twisting the boot, associated with tilting of jaws. Tilting of at least one jaw causes the toepiece to take up a closed configuration, a releasing configuration for releasing the boot as a result of twisting of the boot, or a fitting configuration. The releasing system includes an elastic return for the jaws in the closed configuration and releasing configuration of the toepiece. Connection between a jaw and the elastic return includes at least one transmission link articulated to the jaw about a hinge axis oriented in the longitudinal direction so the jaw and transmission link form a knuckle joint that deforms in the plane corresponding to the transverse direction and vertical direction of the toepiece.
