The present invention relates to an intake manifold (1) or distributor for an air feed circuit for an internal-combustion engine comprising, on the one hand, an intake or plenum chamber (2) of elongate shape and provided at one of its longitudinal ends with an intake aperture (3) and, on the other hand, at least two pipes (4) laterally connected to said chamber (2), said pipes (4) extending at least partially around said intake chamber (2) from their inlet apertures (5) opening therein and having a curved structure over at least a portion of their length. The intake manifold (1) consists of two parts (6 and 7) produced by injection moulding of thermoplastic material and is joined together in the region of peripheral joint zones located on a joining surface (8') crossing said manifold (1). <IMAGE>
