Apparatus for deterring theft of trailers which utilize a tow ring having a central opening and upper and lower annular surfaces. The apparatus assumes the operational position when the upper surface of a base plate is positioned proximate to the lower surface of the tow ring and the lower surface of a top plate is positioned proximate to the upper surface of the tow ring. When assuming this operational position, a tongue integral with and upstanding from the base plate extends through the central opening of the tow ring and through an aperture formed in the top plate. The tongue has at least one hole located between its free end and the upper surface of the top plate to receive the shank of a padlock when the apparatus is in the operational position. A cover member is integral with the top member and overlies the free end of the tongue to protect the lock in its secured condition.
