Abstract: An electrical plug adapter has a plug body, female receptacles in one surface of the plug body, male prongs extending from another surface of the plug body, and a male catch mechanism associated with one of the male prongs and resiliently biased to a catch position relative to the one male prong. The male catch mechanism is configured to catch on an object in a standard electrical outlet when the male prongs are inserted into corresponding receptacles of the outlet. An actuator on the plug body is configured, when actuated, to selectively move the male catch mechanism to a release position relative to the one male prong and allow the male prongs to be removed from the corresponding receptacles. A one-way retention mechanism can be associated with one of the female receptacles and configured to permanently retain a male connector prong from a standard electrical connector plug when inserted into the female receptacles.

Abstract: An electrical plug adapter has a plug body, female receptacles in one surface of the plug body, and male prongs extending from another surface of the plug body. The adapter has a male catch mechanism associated with a latching prong of the male prongs. The male catch mechanism is resiliently biased to a catch position relative to the latching prong. An actuator on the plug body can be moved to selectively move the latch mechanism to a release position closer to the latching prong. The male catch mechanism includes a portion configured to catch on an object in a standard electrical outlet when the male prongs are inserted into corresponding receptacles in the standard electrical outlet.
