Abstract
Abstract A plastic tie down clip including a body and a disc for fastening to a sheet of material. The body includes large internal opening at one end and a smaller internal opening at the second end with a tapered slot interconnecting the openings. The slot decreases in size from the large opening toward the smaller opening. The intersection of the slot and the smaller opening is provided with locking shoulders facing the smaller opening. The disc has an irregularly shaped periphery. The body is placed over the material and the disc is placed under the material and shoved through the large opening carrying the material through the large opening and is moved along the tapered slot to carry the material into the smaller opening and to be locked therein by the shoulders. The irregularly shape of the disc prevents slippage between the material and the disc and acts as a locking device in the small opening of the body.
