1. A conduit through which at least one pipe or cable extends, wherein the conduit has an inner wall and is provided with a system for sealing in a space in the conduit that is unoccupied by the at least one pipe or cable, wherein the system comprises:
rubber elements for providing in the conduit a support-structure which is clamped-in in the space in the conduit that is unoccupied by the at least one pipe or cable; and a sealant layer against the support-structure for sealing off at least one end of the conduit between the inner wall and the at least one pipe or cable, wherein each rubber element is made of a rubber that is fire-resistant vulcanized and thermally substantially non-expandable, wherein the sealant layer is made of a polymer that is fire-resistant and thermally substantially non-expandable, wherein the polymer is vulcanizable at room temperature under exposure to humidity or has vulcanized, wherein the sealant layer has a thickness in a range of 14 to 16 mm wherein each rubber element is a longitudinal element, and wherein each longitudinal element has a length in a range of 12 to 14 cm, wherein at least one of the rubber elements comprises a mantle-wall that is closed in itself.
