From Wiki- Trangia:
General-purpose pot handles, often called billy-grips, can be bought separately. These have a hinged pliers-like construction and can be used to grip almost any pot which has a lipped rim. The term "spondonicle" has also been applied to these handles by some Australian users;[8] it is widely understood that the term is derived from a Three Stooges comedy sketch where the term is used to refer to a mock surgical instrument.
