A fire-resistant seal for gaps between a door or window and adjacent structure, comprises a tubular holder which contains a fire-resistant barrier material and has a lengthwise opening through which the material can exude when the holder is subjected to hot smoke or fire. To protect the material against a tamperer who inserts a probe into the opening, a baffle surface, which is coextensive with the opening, is provided inside the holder. The baffle surface forms with adjacent surfaces of the holder a strait which extends between the opening and the interior of the holder where the material is retained. The holder may also support an elastomeric draught excluder.
