[0003] At the same time, the application number is CN202222431432.0, a pressure-relieving automobile brake hose connector, "including: a No. 1 hose and a No. 2 hose, one end of the No. 1 hose and the No. 2 hose are respectively fixedly connected with a connector kit. The two connector kits are installed by an annular fastener, which can improve the connection strength between the two connector kits and the No. 1 hose and the No. 2 hose, and prevent the No. 1 hose and the No. 2 hose from being pulled out from the two connector kits";

[0004] During use, the existing brake hose joints increase the strength of the hose and improve the pressure limit of the hose, thereby playing a protective effect and preventing the hose from rupturing.
