Abstract
A split nut structure provides the holding power of an ordinary nut on a bolt while allowing for quick release through removal of a retaining sleeve from containment alignment around the segments of the split nut. What could be in many respects like an ordinary hex nut is in three segments, with cuts in three faces of the hex nut to the center, put around a bolt in the same manner as though they were connected and retained in this state by a hexagonal sleeve, the hex inside of which snuggly fits the nut itself. The outside hexagon of the sleeve provides for a wrenching surface by which the nut may be adjusted and tightened much the same as any ordinary hex nut -- however, for quick release the sleeve is merely pulled straight up along the axis of the nut and the bolt.
