The present invention concerns a process for manufacturing the blade of a turbomachine using the lost-wax moulding technique, where the blade includes a first central longitudinal cavity and at least one second longitudinal cavity together forming a cooling circuit and communicating with each other at one longitudinal end via a transverse channel, where the process includes the manufacturing stage of first and second cores corresponding to the said cavities, where the two cores each have an end portion, by which they are connected together, and where the assembly of the two cores is then positioned in a shell mould and the metal poured into the said mould, characterised by the fact that the said end portions, are connected together by an assembly of the mortise and tenon type.
