ABSTRACT:
A lock assembly includes a lock shell formed with a ball-receiving channel which receives a movable locking ball therein and which intercommunicates longitudinally extending and transversely extending holes that are formed in the shell. A flexible shackle is connected to the shell at a first end portion and is provided with a retaining member at a second end portion. The retaining member is insertable into the transversely extending hole and has a peripheral surface formed with an annular groove. A push member is disposed slidably in the transversely extending hole and is biased to slide outwardly of the transversely extending hole. A key plug is received rotatably in the longitudinally extending hole and has an inner end portion provided with a ball-receiving notch. The plug is rotatable between a locking position, wherein the retaining member is inserted into the transversely extending hole and the notch is misaligned with the channel so as to permit extension of the ball into the transversely extending hole to engage the groove of the retaining member in order to retain the retaining member in the transversely extending hole, and an unlocking position, wherein the notch is aligned with the channel and the push member is biased outwardly so as to urge the ball to disengage the groove of the retaining member and engage the notch.
