A shelf clamp for connecting a rack unit to a display shelf has a flat body with a clasp extending from the top end of the flat body, a support lip extending from the mid-section of the flat body, and a front fin extending diagonally upward from the front face of the flat body, wherein the front fin is comprised of flexible material such that the front fin can flex towards the flat body. The bottom end of the shelf clamp is fashioned to slide down between an edge of the shelf and a wall, causing the front fin to flex upward toward the flat body as it presses between the shelf and the wall, and then return to its diagonally upward position once it passes the shelf. Thereby, the shelf clamp engages the edge of the shelf and the support rib and the front fin.
