Abstract: An extension cord clamp for reinforcing a connection between two components attached to cords includes a quadralateral or annular frame with a central opening for receiving the components. Two mutually opposite channels are each formed in the frame. The channels are substantially centrally formed in a respective one of the sides if a quadralateral frame is provided. Two pivot pins are fastened to the frame in the vicinity of a respective one of the channels. Tabs are each pivotable about a respective one of the pivot pins into a closed position. The tabs each have an edge facing toward the central opening in the closed position. The edges each have a respective notch formed therein. Two locking pins are each fastened to the frame in the vicinity of a respective one of the channels for engaging a respective one of the notches and locking the tabs to the frame with the cords in the channels and the tabs in the closed position.
