Abstract
A padlock, which comprises a lock casing and a basically U-shaped shackle slidable therein between a closed and an open position. The shackle has two legs of different length, of which at least one is provided with a locking notch. The padlock also comprises a cylinder lock mechanism, operable by a key, and at least one locking member coacting with a guiding portion of a turnable member of the cylinder lock mechanism for locking the shackle to the lock casing. The locking member is movable dependent on the angular position of the guiding portion of the cylinder lock mechanism between a locking and a releasing position. The releasing position allows the shorter shackle leg to completely slide out from the lock casing. A retaining member is attached to the lock casing in order to keep the cylinder lock mechanism properly fitted in the lock casing. The removal of the retaining member from the lock casing requires turning of the retaining member in relation to the lock casing. A blocking member is dimensioned in its blocking position to be partly received in a recess in the retaining member and partly in an opening in the lock casing. Thereby it prevents the turning of the retaining member in relation to the lock casing. The blocking member is removable from its blocking position when the shackle is in its open position.
