This invention relates to clipsemployed to re

facture againstv displacement from a pocket or
other support and the object of the invention is
to provide a clip-on the class described formed
from plastic material and particularly such ma
terials‘ having a- reasonable amount of spring
properties and materials which may be molded or
die-cast; a further objectibeing to provide means
for reinforcing pl'astic clip bodies of’ the charac

passes through a T-shaped‘ aperture 22‘ in the
fountain pen cap 23 and. adjacent the end wall

The plate 2| has a prong 215
formed from the material thereof; which extends
into the bore of the cap 23. Theprong 25 force
