A fire collar or fire damper for location within a concrete slab of a building. The device incorporates a damper arrangement (12) and a heat detector (18, 19) comprising a metal alloy or lead which melts when a preset temperature is reached, causing the damper arrangement to seal off associated pipework or ducting.
