The invention provides a novel fire-fighting hose pipe joint which comprises an inner cylinder and an outer cylinder. The front end portion of the inner cylinder is provided with a lock catch part protruding outwards in the radial direction and at least one unlocking poking piece rotationally connected to the inner barrel. Containing grooves open backwards are formed in the lock catch part. Poking piece shafts are located in the corresponding containing grooves. The inner surface of the front end portion of the outer cylinder is provided with at least one elastic lock catch which protrudes inwards and can move. Poking piece elastic pieces are arranged between the unlocking poking pieces and the inner cylinder. The novel fire-fighting hose pipe joint is a male and female homebody pipe joint, no matter what emergency circumstances are, as long as there are two pipe joints, the two pipe joints can be connected in a butt manner, only one kind of the pipe joint needs to be prepared, in the using process, either a pipe joint is a male pipe joint or a female pipe joint does not need to be checked firstly, the problem that for a clamping type fire-fighting connector, due to the fact that the male end and the female end are inconsistent, the male end and the female end are taken by mistake during fire fighting, and fast connection cannot be achieved is solved, in the production and manufacture process, only one kind of the pipe joint needs to be machined, equipment management is simplified, and the phenomenon that due to multiple connector kinds, the connectors are taken by mistake is avoided.
