To this end, the expansion gap (19) for the flame-proof lining is arranged in a plane of the cross section of the duct that is adjacent to the plane of the cross section of the corrugated pipe compensator (18) of the steel sheet cover (15). The steel sheet cover (15) is separated at the circumference in the area of the expansion gap (19) for the flame-proof lining so that after release of the releasable connection (23, 24) of the steel sheet cover elements (21), the elastic temperature-resistant jointing material (20) is easily accessible from outside the duct.
