Abstract
A lock-in adapter having a locking arm ending in a latch contained within a ground pin for securing the adapter into a wall outlet via the ground pin receiver. Internal locking arms similarly lock and retain a plug inserted into the opposite end of the adapter, thereby securing the plug to the adapter and the adapter to the wall. The adapter can be further secured to the outlet faceplate via screws through tabs located on both the top and bottom ends of the adapter. A button secures the various latches to secure the plug and adapter, and which can be selectively operated to release both the adapter from the outlet and the plug from the adapter.
