A locking electrical plug (1) including a securement arm (18) residing in a securement arm slot (32) located in the flat of a power blade (16). The securement arm (18) is normally biased orthogonal to the flat of the power blade (16) by a spring (15) and instruction member (20). In the normal locked position, the securement arm (32) extends outward from the securement arm slot (32). A mechanical catch located on the securement arm, or alternatively friction, is used to resist the extraction of the locking electrical plug (1) from a conventional electrical outlet. User operation of a mechanical pushbutton releases the lock by pushing the securement arm, against the spring force, into a recessed position in the securement arm slot (32). The locking plug (1) may be extracted from the electrical outlet through the application of a predetermined force without direct operation of the release mechanism.
