ABSTRACT:
An anti-snooping device for doors to apartments comprising a locking mechanism and a relatively low-strength, "tamperproof" seal capable of engaging the locking mechanism, the locking mechanism being capable of disengagement without, however, compromising the "tamperproof" seal. The invention's preferred embodiment is a chain door lock in which one of the chain's links has been replaced by a coded, colored, plastic, "tamperproof" seal. To enter the apartment, the apartment dweller uses, first, her door key and then, second, the key to or, alternately, the combination of, the anti-snooping device. Entry by anyone else must be effected by breaking the "tamperproof" seal or by breaking or successfully picking the anti-snooping device's lock.
