Protective apparatus for a lock and a lock including such apparatus are disclosed. The protective apparatus comprises a plate-like element adapted to be added to a standard lock without requiring any mounting structure not already present in the lock. A spring causes the plate-like element to move or pivot when the connecting bar of the lock is removed to block the opening through which the lock connecting bar extends into the housing. Thereby, the plate prevents insertion of a tool such as a screwdriver into the lock. In some embodiments, the protective apparatus locks the bolt when the connecting bar is removed.
