Abstract
A device for sealing off tubes passing through walls or ceilings has at least one tube sleeve (76) to be attached to a wall or ceiling (10), said tube sleeve being lined on its inside with a fire-proof expanded material (34) expandable to the inside under the effect of heat. On the inside of this tube sleeve there is a sound-insulating material (36, 38).
