Splice sleeve for corrugated pipes, especially pipes for electrical installations and of the kind formed of plastic material, characterized essentially by the fact that such sleeve is of elastic nature, has, at least on its internal face, transverse corrugations with a separation equal to that of the corrugations of the two tubes to be joined and a minimum internal diameter somewhat smaller than the maximum external diameter of those tubes, in such a way that the external nerves of the latter, when the junction takes place, penetrate into the recesses of the undulations of that sleeve.
