A structure for connecting a branch pipe in a high-pressure fuel manifold employs a nut to fasten the branch pipe to a main pipe, the nut having threaded surfaces which are simultaneously brought into thread engagement with the branch pipe and a coupling member which is secured to the main pipe in such a manner as to surround the peripheral wall thereof. Therefore, it becomes unnecessary to conduct a welding operation which has heretofore been needed to connect the joint portion of the branch pipe to the main pipe. The connecting structure satisfactorily endures ultra-high fluid pressure even under vibrations. In addition, there is no fear of fuel leaking out through the joint nor risk of the branch pipe coming off. |
