Abstract
A lock case interlockable with an anti-theft latch is mounted on a door. The lock case includes a latch coupled with a latch hole in a door frame for retaining the door in a closed position. The anti-theft latch can be operated to engage with the door frame. When the latch is picked, the anti-theft latch still remains engaged with the door frame to prevent opening of the door. When normally operated, an inner operating device or an outer operating device can be operated to disengage the latch from the latch hole while disengaging the anti-theft latch from the door frame, permitting easy, convenient opening of the door.
