A belted chain connection system includes first and second flexible belt portions, each flexible belt portion having first and second ends with integral lugs extending therefrom. A non-circular aperture extends transversely through the integral lugs, and a reinforcing ply is embedded within each flexible belt portion, the reinforcing ply having a continuous portion substantially circumscribing the non-circular aperture in each lug. A non-circular pin is configured to extend transversely through aligned non-circular apertures of the lugs of the first and second ends of adjacent belt segments, to non-rotatably connect the adjacent belt segments.
