  • Phone jack lock
    Patent number: 5340324
    Abstract: A phone jack lock that is molded to the contours of a standard phone jack. When the lock is installed, a spring-loaded locking element protrudes behind the outer surface of the phone jack so that the lock cannot be removed without the key. All elements of the lock are contained within the contours of the interior of the phone jack, so that no element extends beyond the external surface of the jack when the lock is in place, i.e., the locked jack has the same profile as the unlocked jack. The lock may be used without installation effort or tools.
