A foam generating device for a fire hose, comprising a socket designed to be attached to a water supply hose, a hose nozzle consisting of a first end wherein air inlets are made and of a second end for spraying the foam, an intermediate body attached between the socket and the first end of the hose nozzle and allowing the creation of several separate water jets passing through. The intermediate body is so arranged as to receive an emulsifying fluid and to pre-mix it with the water jets by aspiration and by contact of the emulsifying fluid with the water jets, then to spray the jets of water-emulsifier premix and to stir them with the air streams in the hose nozzle.
