A manifold for conveying a high-pressure fuel comprises a main pipe having an axial bore and a plurality of ports formed through its wall, connected with the bore and spaced apart from one another along the length of the pipe, and a plurality of branch pipes each connected at one end thereof with one of the ports. The main pipe is provided with a plurality of short cylindrical projections extending laterally outwardly from its wall and each having an axial bore defining one of the ports. Each projection has an outer end provided with a conical or spherical surface, and an outer peripheral surface provided with a screw thread. Each branch pipe has a diametrically enlarged connecting head having a frustoconical or spherical surface closely fitting the conical or spherical surface of one of the projections. A cap nut surrounds each branch pipe and the corresponding main pipe projection and cooperates with the screw thread on the projection for holding the surface of the head against the conical or spherical surface of the projection.
