Abstract: Individual fasteners are provided for each of several pre-determined holes along a margin of pages of a document for securing the pages together at the holes, each fastener including: a relatively rigid cylindrical insert having a head at one end, the diameter of the insert cylinder being less than the diameter of the holes in the page and the diameter of the head being greater than the diameter of the holes; an elastic member such as a rubber elastic extending from the insert to a bar and attached to the center of the bar, the length of the insert cylinder being less than the minimum thickness of pages to be bound by the fastener and the length of the cylinder plus the length of the bar being greater than the maximum thickness of pages to be bound by the fastener.
