How about those little two-hole or three-hole
telephone-wire squeeze splices; you know, the
ones with the red or yellow button? They're insulation-displacing,
have a dab of goop in them, and couldn't be easier
to use; just inster and squeeze. (Edit: Let's
make that "insert")
I have been using those for years, just strip twice the length of the IR wire and double up for girth so the crimp has enough to grab.
