A dual-flow band screen includes a carrying frame and a screening band which is mounted so as to move in an endless loop on the frame. A support wall is associated with the carrying frame, which support wall overall extends perpendicularly to generatrices of its screening band, while possessing an opening opposite the latter, and which support wall laterally forms engagement lips by means of which it is capable of engaging with the guides in a sluice.
