Abstract
A clamp nut 10 comprising a split threaded nut 12 for engaging a threaded spindle (not shown), a coiled spring 16 encircling the split nut 12, means 20 for holding the spring 16 tightly coiled around the split nut 12 and a cap 30, engaging the spring 16, which can be turned in a first direction (A) to tighten the spring 16 around the split nut 12 and in a reverse direction to release the holding means 20 thereby loosening the spring 16 around the split nut 12 and enabling the split nut 12 to expand radially to facilitate removal of the clamp nut 10 from a threaded spindle. The mechanism for releasing the holding means 20 preferably includes a cam surface 32, formed integrally with the cap 30, which lifts an end 19 of the coiled spring 16 off a set of ratchet teeth.
