The locking member includes an exposed keyway which is selectively aligned with at least one slot in the shoe located at the recess. The pivot bar has an arm which functions as a key for fitting in the keyway and has at least one projection extending outwardly from the arm for fitting in each slot when the slot and keyway are aligned.
