Improvements in the systems of elastic, internal unión, for pressure ducts, particularly for ducts formed by tubes of cement-based materials, characterized in that they consist of internally mounting between the ends of two tubes to join a sleeve whose inner surface is cylindrical in its entire length and has a diameter substantially equal to the inner diameter of said tubes to be joined, and whose outer surface is cylindrical for most of its length between the ends, and frustoconical at each end, with the minor base facing outwards.
