Abstract: An apparatus and method are provided for substantially avoiding the inadvertent disconnection or dislodgment of an electrically powered device, such as a computer or television set or vacuum cleaner, from a source of electrical power. The apparatus includes an electrical male plug that has prongs configured to increase the tension between the electrical male plug and the sockets of an electrical power outlet, or an electrical female plug that has female contacts disposed in sockets and configured to increase the tension between female contacts and the male contacts of the electrically powered device. The apparatus and method alternatively provide an adapter having an increased tension electrical male plug at one end and a standard electrical female receptacle at a second end, and a mechanism that locks a standard electrical male plug to the standard electrical female receptacle of the adapter.
