A first fastening station and a second fastening station are defined on said actuation arm and configured to fasten the control cable in different positions on the actuation arm. An anti-rotation appendage projecting from the chain-clamping washer is adapted for being inserted in a holding seat of the actuation arm and holding the control cable in at least one of the first and the second fastening stations.
