Abstract
An electrical cord locking connector joins electrical cords in series and presents a streamlined profile that minimizes interference in restricted spaces through which the cords must be fed to service a job site. The connector joins the ends of successive cords utilizing the outwardly projecting shoulder provided on the female socket of one cord in cooperation with a latch member on the male end of the connecting cord to lock the two cords together.
