A locking, non-catching electrical cord has smoothly rounded edges so as not to catch on foreign objects. The male prongs of the extension cord taper from the end of the cord to a rounded end of the same height, and the prong receptacles are shaped to fit the male prongs, so as to allow the prongs to snap-fit into the receptacles. Alternatively, the prong receptacles may have two cavities skewed from one another, and the male prong end of the cord may be twisted once situated within the prong receptacle to create a locking fit.
