The spray mouthpiece device for a fire extinguishing system comprises partly a pipe coupling with a connecting support, partly a coupling socket on a coupling support, and partly a mouthpiece fixed to the connecting support by the coupling socket. The mouthpiece is formed in one piece with a sealing component, which has a blunt conical sealing part, which with the aid of the coupling socket is pressed into the connecting support. |
