The latter with a simple coin screws screws (3) within suitable orifices formed on strip (1), the latter being fixed to the internal surface of the folder. There is also provided that each ring (2) may be closed simply by causing projections (5) which are formed on the base of each ring to penetrate within shaped grooves (4), the latter being formed at the opposite end of the same ring, an operation which is easy due to the elasticity of the material which constitutes the rings.
