The locking apparatus includes a "Y"- or "y"-shaped shackle with two legs, or an "E"-shaped shackle with three legs, each leg having a free end, and a locking cross bar with openings positioned to receive the free leg ends and a locking mechanism to lock the free leg ends of the shackle in the cross bar, thereby locking the locking apparatus.
