Oh, Those are for the track, too. The tips of them is what you put the tubing on. Their not any different then the yellow connectors. They just have a tip that you can stick tubing on.

They were made for the original k'nex coaster. It's a red rod wide so to keep the track from squeezing together, they made the nubs.
