A device for stripping material from a conveyor belt conveyor. The device includes a stripping body which can be pulled against the conveyor belt by means of a carrying element, a fastening device, and a tensioning device for the carrying element. In an installed state the carrying element is connected to the fastening device at one of its end and is connected to the tensioning device at its other end. The tensioning device has a spring, a stop for supporting the spring and a traction rod. The traction rod is connected to the carrying element. The spring is arranged in a receptacle associated with one or more adjusting means defining a through opening as a passage for the traction rod. The receptacle or the respective adjusting means defines a reference point for setting a variable tensioning force which corresponds to a desired tensile force dependent upon said angle.
