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.

Abstract: The mobile binding consists of two sheets (1 and 2) of cardboard, or similar semi-rigid material, which extend over the whole length of the binding and which are stuck to each other, except at least in the end portions of the spine, and an opening (8) is provided in the inner sheet of cardboard, perpendicular to each of these end portions. The elements holding the magazines consist of clips (9) substantially in a S-form one (9a) of whose end branches is designed to be inserted into the middle of a magazine to be bound (10); the other end branch (9b) is designed to be inserted through one of the openings (8) of the inner sheet of the spine. Each clip (9) is in molded plastic, its central branch (9c) being extended to beyond the portion (9e) where it connects to the first end of branch (9b), by an overlay (9d) in the immediate proximity to the inner sheet.
