For sealing the outlet slot (111) on the roller-shutter box (11), it is proposed to surround the outlet slot (111) with seals (21, 21%) extending across the length of the slot (111), up against which, when the roller-shutter armour (12) is pulled up (arrow A), stops (22, 22%) run, which, extending across the clear width between the lateral guides for the roller-shutter armour (12), are assigned to the end slat (129) and project covering the outlet slot (111). <IMAGE>
