The present model is constructed and functions in the following manner: Structure: Two bodies made from plastics, specifically from polypropylene, manufactured by means of injection- moulding, forming a base with two tubes and four holes for fixing to the filing system, and the other body consisting of two articulated plastics pieces with the base designed so as to close the support. Functioning: The respective support is fixed to the file or filing system by means of four rivets (bolts). The articulated movement on the base of the two pieces of the second body allows the insertion and removal of the sheets in the filing system without it being necessary to remove all the preceding sheets, and this can be done in any sequence, also allowing its front/back movement. <IMAGE>
