ABSTRACT:
The connector is capable of securing a cord to an outlet, of securing extension cords, and/or of securing an extension cord to the cord of a power tool. The device may have a female receptacle and a male plug, only a female receptacle, or only a male plug. The female receptacle may have a screw-style plunger, a sleeve-style plunger, or other means for applying pressure against the sleeves holding the prongs that are plugged into the receptacle. The male plug can use a sleeve-style plunger or other means to apply pressure against at least one of the prongs, causing the plug to be clamped into a receptacle. The female receptacle and male plug of the device can be separated by a cord to create an extension cord. The female receptacle or male plug could also be placed on the cords of a tool or appliance. A plurality of female receptacles could be used in a single unit to create a power strip having locking receptacles.
