Protective insulating tube for electrical installations, characterized in that the joining bend formed by the edges of the metallic envelope, is provided with a succession of portions in relief, produced by the pressure of a roller with hollow-reliefs in a convenient manner, with that said reliefs produced in the closing fold, cause the incrustation of the edges of the envelope one in another, giving rise to a secure connection and avoiding the eventual separation of both parts.
