ABSTRACT:
In a preferred embodiment, a string of Christmas lights includes a plug adapted to receive an electrical fuse within a lower insertion opening in the plug-face from which the male prong elements extend from the plug such that when the plug is withdrawn from a socket a fuse may be inserted or withdrawn, the insertion opening for the electrical fuse being continuous with a fuse-holding channel having at a far-end thereof a small opening too small for insertion or withdrawal of the fuse, through which small opening an object may be inserted to press-against a fuse within the channel in order to push the fuse out-of the lower insertion opening while maintaining the plug in an assembled state.
