A padlock has a lock body, a shackle, a lock bolt, and a lock bolt control mechanism. The shackle comprises two parallel arms capable of being retained and locked respectively in two receptacles of the lock body. One of the two arms can be drawn to become detached from the lock body. The lock bolt is caused to move to join with the end portion of one of the two arms at the time when the end portions of both arms are retained and locked in the two receptacles. The lock bolt control mechanism is housed in the lock body and is connected with the lock bolt. The lock bolt control mechanism can be caused by a key to move from a locking state corresponding to a connecting position of the lock bolt to an unlocking state in which the lock bolt is caused to move axially from the connecting position to a disconnecting position which is not corresponding to a bolt connecting portion of the shackle arm.
