The fastener is rotatable between a clamping position and a non-clamping position by means of one of two keys. One key being capable of engaging one of the fastener's ends, and the other key being capable of engaging the other of the fastener's ends. This is particularly convenient for circumstances where the approach to one or the other of the fastener's ends may be obstructed.
