Disclosed is a fire extinguishing apparatus for airdropping a fire-extinguishing agent which comprises a flexible tank containing the fire-extinguishing agent, a base section attached to the lower portion of the tank and including a valve for discharging the fire-extinguishing agent, a head block attached to the upper end of the tank, whereby the whole body of the apparatus is suspended, and a support with its upper and lower ends coupled to the head block and the base section, respectively. In this apparatus, the coupling between the base section and the support is achieved by way of a bayonet coupling system using upper and lower coupling members attached respectively to the base section and the support. When the coupling between the two coupling members is completed, a coupling retaining member slidably fitted in the support engages both these coupling members to lock the coupling between them.
