Pip Pin - Presenting a classic quick release pin.
This pip pin website is provided to recognise a now obsolete part of
engineering, a classic quick release pin, manufactured in England by
Avdel® up until the late 1990's - the pip pin.
A double action pin fastener,
it could be release by pulling or pushing the ring, thus allowing rapid
removal of the quick release pip pin from a locked position.
