Abstract
A form has a zigzag shape, around which an associated electrical cord is wrapped over and under a plurality of times. The form preferably includes at least a portion having a shape corresponding to one of a sine wave, a square wave, a triangle wave, a continuously curved wave, and a “Z”-shape. The form is preferably retained near an electrical device by a retaining element. The retaining element preferably includes at least one of a partially blocked conduit, a narrowing conduit, a partially blocked tube, a bent tube, and a narrowing tube. The conduit preferably receives the form therein. The interfaces of the associated cord and the form preferably effectuate a frictional locking therebetween.
