A Colleg case back

Although it is not as widespread and common as the other elements dealt with so far, many models have, usually associated with their loading mechanism, a case back that covers the rear part (in relation to the nib) of the body of the pen. This element is not always present, as for many pens the back end is simply part of the shaft of the pen. A photo gallery of different types of knobs can be found here.
