Spade ... blade....

I thought they were the same thing so obviously I don't speak American

This UK terminal catalog uses the terms blade and spade for the same
catalog items, so it's not just me.

Ring Lug - a closed loop shaped like an O
Spade Lug (blade) - an open end shaped like a U
Hook Lug - a open end shaped like a ?

The basic undying question is why are ring lugs to be used instead of
spade? It has to do with trying to prevent a connection failing due
to vibration. If the terminal screw works loose, a spade lug would
fall off while a ring lug will hang on (and the loose screw will
hopefully be caught during inspection). Now this is more of an issue
in powered airplanes due to the constant vibration from the engine.
Still gliders have to live by these rules too.

Faston - Shaped like a, ummm, hmmmm, well, that's kind of hard to
explain. From the end they look like a C that was flattened by a
hammer so that the ends are curved inward. They make a very tight
connection to the mating part which is a narrow flat piece of metal
(like on typical gel-cells). It is a male-female connection.
