A connector assembly that enables a rope or other load to be attached to a tarp or other sheet material. The assembly includes male and female connector members having broad, flat base surfaces for engaging the material of the tarp from opposite sides. The male connector member has a sharply pointed screw portion for penetrating through the material of the tarp, and the female connector member has a threaded socket for receiving the screw portion of the male connector member. At least one of the connector members includes a projecting flange portion having an opening or hook for attachment of the rope or other load. The flange portions are flattened for being gripped between the thumb and forefinger when tightening/loosening the assembly. The grip faces of the connector members include raised protuberances that prevent accidental loosening during use.
