Abstract: A ski binding comprises a first recess for receiving a ski shoe pin, a locking member movable between a locking position and a open position, a biasing means to bias the locking member towards the locking position, and an activation member rotatably attached to the housing for rotation around a transversal rotational axis of the binding. The locking member has at least one outer portion that allows a ski shoe pin to force the locking member from the locking position towards the open position when the ski shoe pin enters the first recess. The activation member has an arm extending radially away from its transversal rotational axis. The activation member and the locking member are operatively connected such that when the arm rotates in the first rotational direction through a predetermined lower operational range, the activation member forces the locking member from the locking position to the open position.
