I'm working with the 80 gl1100 wiring schematic and see the term, "tube" in a number of places. Is it safe to assume these are tube connectors for joining 2 wire ends?

Actually I think what you are looking at is color coding tubes. I bet if you look, you will see lets say "OR tube" on your diagram, if you find that wire on the bike it is probably a black wire with an orange band (or tube) on it near the plug.
Interesting...I read about this and found a single entry for the word "tube" in the electrical section.
It's as shown here..
.I am speculating that in some wiring bundles,there may be a colored band attached around it (in a tube fashion) as a form of identification like this...
