This invention helps to improve the safety of door locks. It is achieved by making the bolt of the lock in a locked position to catch on a locking box or plate, significantly encumbering its prying open. The door lock (shown in an unlocked position on Figure 1) consists of a lock mechanism with a key, a case (1), where along the taker (2) of the bolt (3) with notches (4, 5) and a cam (6), axes (7, 8) and a locking box or plate (9) are situated. When the lock is in the locked position, the bolt (3) with its cam (6) catches on the locking box or plate, because the bolt (3) with its profiled notch moves along a stationary axis (8).<IMAGE>
