Like most plugs, there are different types. Some have a screw-on ferrule
that that fits over the metal "plug" end and traps the end of the wire.
First, you unscrew the plastic 'handle" from the metal plug. Then you
feed the wire through the handle into in the back side and it will come
out a little hole at the "base" of the plug section. You wrap it around
the base of the plug and replace the ferrule over the plug and it grips
the wire securely.

I prefer solder. All of the plugs I have seen have a hole in the back
that is exposed by unscrewing the plastic "handle" part. I place the
wire in the hole use my big (275 watt) Weller soldering gun. It quickly
heats the plug enough to melt solder into the hole and secure the wire.
Be sure to put the wire through the "handle" first! 

Holding them for soldering can be fun, especially if you don't want to
bend the spring leaves on the plug. I use a small bench vise with a
couple of strips of wood to avoid crushing the plug. The wood also
prevents the vice from absorbing all the heat!

...how does one connect banana plugs? I have never used them and don't
have a very good idea as to how to secure wires to them. ...Bruce - W8FU
