Abstract
A holder with a stack of sheets, each of which is provided with a hole through which a pin passes, the sheets being provided with a slot that extends from the hole to the edge of the sheet, and a cutout that is diametrically opposed to the slot. An annular part formed from a thin plate of stiff and, optionally, easily bent material is secured to the pin. This passes obliquely upwards through the slots and cutouts in the sheets and is arranged with about one half beneath the stack of sheets, the other half being above the stack (FIG. 4).
