Abstract
In a pack of substantially parallel-stacked transportable washers, at least two through-holes are provided in each washer, the two legs of a substantially U-shaped metal or plastic wire being positioned in the two through-holes of the stack of washers. The free ends of the legs projecting beyond the stack are bent over to positions oriented at approximately right angles to the respective legs. By appropriate force on the crosspiece, or on an extension, the wire is pulled back out of the stack of washers, the free ends being restraightened in the process.
