Fire-extinguishing system for buildings, tunnels, public facilities, hospitals, etc. comprises at least one extinguishing agent line (1) fed via at least one extinguishing agent source. A number of recesses (9) in the extinguishing agent line are released when the extinguishing agent line is heated in the presence of fire.
