A double-belt conveyor band with a continuously revolving conveyor band, the belt of which is supported on a band feeder and in connection with a steep segment on trough roller assemblies, and is supported flatly on the steep segment, as well as with a continuously revolving covering band. The belt is buckled in the conveyor seam for the formation of closed conveyor spaces, preferably between traction reinforcements positioned externally, the shear-resistant lateral reinforcements acting in cooperation therewith. The belt ends are pressed on one another and the longitudinal edges of the belt are held together. It is provided in accordance with the invention that, in order to hold together the belts on both longitudinal edges of the cover band, fasteners projecting externally are provided with opposing apertures to which the longitudinal edges of the conveyor belt, during the running of the trough roller assemblies, approach or move away from during the running of the conveyor belt.
