ABSTRACT:
A ring binder to be fixed to an article has a support for mounting a plurality of ring members thereon and a control member for opening and closing the ring binder. The support has a pair of support members pivotally supported by a holder joining the outer edges of the support members together, whereby the inner edges of the support members move away from each other on pivoting. The holder cooperates with the control member in order to support the support members. The ring binder may also include one or more securing elements for holding the support members by extending across from the outer edges of the support members and cooperating with the control member, and fixing elements below and connected to the support members.
