Abstract
A sliding shackle padlock for securing an outwardly opening door or closure provides a tapered shackle for cooperatively engaging the staple of a hasp or another fastening member on the door or closure, which may be removably secured to a door jamb. A protective cover is provided to conceal the locking arrangement between the tapered shackle and the staple or other fastening member. A ratchet arrangement or a spring clip arrangement is utilized to maintain the shackle in the shackled position within the staple or other fastening member.
