Device for opening envelopes, which is essentially characterized in that it consists of a piece of resistant material arranged and glued at least along one of the edges of the envelope, so that one end of it protrudes slightly by a vertex contiguous to the reference edge forming an appendix provided with the just and sufficient measurement so that, pulling it with the fingers, the rupture is verified by tearing of said edge and, consequently, the opening of the alluded envelope.
