So why the latter?

It might originally have been called duck tape. See the Etymology section of
the Wikipedia article.

http://en.wikipedia.org/wiki/Duct_tape

The issue is confusing, because it wasn't used for ducts until long after it
was invented.

And what is worse is that the stuff commonly called "duct tape" - fabric
tape with a silvery but non-metallic coating is actually a very bad choice
for sealing ducts. There are varieties of tape that are made for sealing
ducts but the common "duct" tape is not one of them.

I am surprised that no one has mentioned gaffers tape.
