Abstract: A power outlet, and associated method, for an electrical power supply strip. The power outlet includes a housing, an electrical connection for receiving first electrical power type, electrical components to change the first electrical power type to a second electrical power type, and a connection interface to supplying the second electrical power type. The power outlet housing has a body with a shape that corresponds to a shaped aperture of a main housing of the strip. A front portion of the power outlet housing is larger than the shaped aperture. An elastically deformable arm extends from the body and deforms as the arm passes through the shaped aperture of the main housing. An engagement portion of the arm retains the power outlet housing relative to the main housing.
