Abstract of the Disclosure An improved clamp arrangement for attaching a shank particularly an S-tine shank, to a rectangular beam of an implement. A bracket is positioned against two adjacent faces of the beam and includes a formed end with a continuous transition zone which partially wraps around the front edge of the beam to prevent the clamp and shank from rotating horizontally. The formed end also provides increased depth of section to increase the bending strength of the bracket.
