ABSTRACT:
A mobile binding is provided comprising holding elements or S shaped clips and formed from two sheets of cardboard, or a similar semi rigid material, which extends over the whole length of the binding and which are bonded together, except at least in the end portions of the back, the inner sheet having an opening in which one of the end legs of the S shaped element may be engaged, the other end then being engaged in the middle of a review to be bound. The improvement consists in providing said holding elements with a notch on the inner face of their portion situated opposite said opening when they are in position in the binding; it also comprises a plate which may be engaged in said opening between said two sheets of the back and which is provided with an outwardly turned flange adapted for engagement in the notches of said elements.
