Abstract: The invention provides a fluid transfer pipe for filling a cooling circuit of a motor vehicle, and the method for manufacturing said pipe. This pipe includes at least one corrugated bendable portion based on at least one thermoplastic material and which includes a succession of radial reliefs axially spaced so as to form hollows between them, each relief having two frontal regions linked together by an intermediate region, the frontal regions of each relief each having one and the same overall polygonal contour defining at least three straight sections forming flats for this relief and interlinked by rounded sections forming bulges, and the contours of the successive reliefs being adapted to allow for the stripping of the corrugated portion from two hemicylindrical shells of a mold along a single axial stripping plane.
