US Patent 7425146 Lock-on boot

A lock-on boot for preventing a double-ended cable from becoming detached from a motor disconnect switch, includes a cover, a retaining rail, a locking mechanism, and a hinge. The cover has two convexly curved shells, each with an inner wall, an interior end, and an exterior end. The retaining rail is mounted on the inner walls within the convexly curved shells for dividing the shells into first and second pockets. The locking mechanism secures the convexly curved shells together and protrudes along their exterior ends. The hinge extends along the convexly curved shells pivotally joining their interior ends so that the convexly curved shells are movable between open and closed positions.
