An improved closure for bags, of inviolable closure character, characterized essentially by the fact of comprising two elements of which one of them is a ring of flexible material and the other a disk washer, whose plane is provided with radial grooves that do not come to the periphery of the same serving this set to condition the pleated material from the mouth of the bag, which for this purpose is passed through the ring forming a fold on it, and by the fact of making it slide along the ring and pass over the fold of the bag the slotted washer, which yields in the direction of its advance by bending its radial teeth which when they are on the fold are in a position that prevents the removal of the ring that becomes inviolable due to the impossibility of retiring under pain of deteriorating the bag in question.
