Abstract
Binding strips are used to bind punched paper. A first strip has studs fitting through the holes in the paper and in a second strip. In one form of the invention the studs are flexible and are bent over to snap into grooves in the second strip so that the studs may be unbent to add or remove paper. In another, more permanent, form the studs may be cut off and riveted to the second strip. One of the strips or an intermediate strip has lateral ears formed with hooks which fit over the conventional parallel bars of suspension-type file drawers. One of the strips may be formed with file tabs to indicate the subject matter of the bound paper. Such file tab may be notched to facilitate removal of a pressure-sensitive label affixed to the tab.
