The inner collet includes a base portion configured to rotatably engage the head portion and a pair of engaging portions defining a slot configured to receive a connecting rod therein. The outer portion is movable relative to the inner collet between a locked position in which the outer portion causes the pair of engaging portions to move toward each other and an unlocked position in which the outer portion causes the pair of engaging portions to be spread apart to facilitate insertion or removal of the connecting rod.
