1. A quick release cam lever assembly for use with the collar of a collar clamp to secure a shaft when received by the collar, the collar being an open-ended ring with outwardly directed opposed flanges spaced apart from one another by a gap between the ends of the ring, and the cam lever assembly comprising:
a cam lever having a first end region terminating in at least one cam element, the cam element being rotatable about an axis of rotation of the lever; and
a fastener with one end coupled to the cam element and having an opposite end for passage through one of the flanges of the collar and being securely mated with the other said flange, wherein the cam element is for exerting a force against the one flange to draw the flanges of the collar together for clamping of the shaft by the collar when the fastener is inserted through the one flange and securely mated with the other said flange and the cam lever is rotated about its axis of rotation from an open position to a locking position, and wherein the cam lever is L-shaped to allow an opposite end region of the cam lever to overlie the flanges of the collar and the fastener in a lengthwise direction of the fastener when the cam lever is in its locking position.
