An apparatus for connecting and anchoring tarpaulins, includes a polymer plastic elongate body having a first side, a second side, and a longitudinal axis. An integrally formed first connector and second connector extend parallel to the longitudinal axis for the entire length of the elongate body. The first connector has an opening facing the first side. The second connector has an opening facing the second side. Integrally formed anchoring wings underlie the elongate body, with a first side of each anchoring wing protruding past the sides of the elongate body. The second side of each of the anchoring wings merge into a vertical plane positioned along the longitudinal axis of the elongate body.
