A locking device for maintaining two electrical cords in firm contact with each other comprises a longitudinal bar, a portion of its surface being serrated, a fixed end member secured to one end of the bar and an adjustable moving locking member slidably mounted on the bar adjacent the other end thereof. A plug and a socket connected thereto are positioned between the two members with the locking member being adapted to form a binding engagement with the serrated portion of the bar thereby preventing the two cords from being separated.
