Ring device for changeable sheets, characterized by the fact of being constituted by two flattened, equal rulers, located with longitudinal edges intestates, and having on the opposites a succession of arched arms capable of coinciding to integrate rings, and ensuring the assembly of the two rules by means of the coupling of a dorsal profile, grooved, that has bent margins to lodge under pressure in longitudinal regattas provided in the rules, which profile tends to keep the edges intestados tightly pressed against each other, and determining in them an axis tilting by which the rules can adopt two unique stable positions, one of which is bounded by the free ends of the arched arms to coincide to form the rings, and the other is limited by coincidence in expansions located on two levers layered provided one at each end of the rule.
