ABSTRACT:
A miniature decorative electric lamp assembly includes an electric bulb inserted into a lampbase member, with the lampbase lower end being received in the upper end of a central longitudinal passageway in a socket member which contains dual electrical contacts each connected to an insulated wire. The lamp assembly also includes an external interlocking device for which the lampbase upper portion includes an elongated semi-flexible radial extending tongue element which has an outer biased elastic detent portion, and the socket member includes a rigid radial frame element having a central opening. During lamp assembly the lampbase member is inserted into the socket member and the internal electric contacts are made and the tongue detent portion is hooked into the frame element, so that the two members are locked firmly together so as to preclude any inadvertent separation and electric disconnect during handling or use.
