PROBLEM TO BE SOLVED: To provide a coupling fitting of a fire hose which has a pair of coupling cylinders of the same structures, can be coupled with the other metal fitting irrespective of types of a male and a female, has compatibility with a Machinosiki metal fitting composed of a pair of coupling fittings having existing distinction in types of a male and a female, is easy in operation and simple in structure.SOLUTION: In order to solve a problem that coupling should become possible by the slide of the bracket, initial activity should quickly be performed, and a fire should be controlled in an initial stage, extensions of hoses should be coupled to each other and pushed in each other. |
