A noise-attenuating fluid transfer conduit, in particular for a pilot-controlled power steering system of a motor vehicle, the conduit being mounted in a high pressure circuit for connecting an electrically-driven pump to a controlled member which is fed with pressurized fluid from said pump, said conduit being made up of alternating segments of rigid tube and segments of flexible hose, and at least one noise attenuator housed inside the conduit, wherein the flexible hose segments of the conduit are of a length which is determined as a function of as short as possible a response time associated with their volume expanding when the electrically-driven pump is set into operation.
