Abstract
Improved element for change rules and the like, characterized in that it is constituted by two symmetrical bodies, transparent, joined by their longitudinal edges, the smaller edges being separated for the introduction by them of the exchange rule or the like, and having both smaller edges, some fingerprints, and presenting a silk-screen printed signal arranged vertically in each body so that they coincide once the two bodies are joined.
