Abstract: The present invention is for an electrical extension connection lock and protector. The designed hard casing surrounds the male and female ends of two cords where they abut and has a housing having a cavity therein with sufficient space to enclose the abutted ends, and having parallel apertures sized for electrical cords to pass out each end away from the protected connection point of the two electrical or electrical extension cords. An electrical cord gripping collar is positioned at each aperture opening, and soft material is used to seal the two halves of the protector when the hinge is closed, joining also the two halves of the parallel aperture collars, thus creating a sealed cavity. The soft aperture collar is formed of two semicircular matching junctures made of soft and pliable material having formed, when closed or joined, a smaller inside aperture through which the extension cord wire can pass, but is intended to press against all sides of the cord to create a water resistant seal.
