A chain scraper conveyor with conveying chute includes a central guided tension chain and catches attached thereto, which are guided in the chute walls. The catches have undersides with a chain link holder assembly for an O-shaped chain link arranged parallel to the chute floor, and the chain link holder assembly includes a stirrup holder and a chain stirrup which is placed on the chain stirrup holder with the positioned chain link, and the stirrup is also positioned in the chain stirrup holder with the chain stirrup clamping the chain link into the chain stirrup holder in the area of its center. A set-screw is provided on each of the stirrup ends, which are set with play into a corresponding bore in the catch and secured by a nut on the other side of the catch. The chain stirrup is stretched into the stirrup holder with a curved elastic deformation, whose curve lies in the plane of the catch, and mounted on the chain link.
