1. A rotor for a squirrel-cage asynchronous rotating electric machine, comprising two compacting elements clamping a cylindrical magnetic mass, shorting discs interposed between the magnetic mass and the compacting elements, and conductive bars housed in housings of the magnetic mass and uniformly distributed over at least one diameter of the magnetic mass so that the shorting discs and the conductive bars form a squirrel cage, at least one of the compacting elements and of the shorting discs comprising insertion holes each disposed facing one of the housings, characterised in that retaining means are inserted into each insertion hole to retain the conductive bars in the housings.
