Clark,

If you bought the "rubber/pliable plastic" replacement, one end of what you bought "snaps" into the hose connection to keep dust out, the other end is like a "rubber band" and just stretches over the "hose swivel" (as you call it). It doesn't appear to stretch that much, and you may need to drop it in a pot of boiling water to "soften it up" a bit so it will stretch, but it's designed to slip over the hose fitting.

Most of us have found that the "snap in" type of dust cover doesn't stay put very well. That's why many of us have replaced it with a "screw in" plug type dust cover. They seem to remain in place much better. Cost is about the same for either, and both kinds are stocked at most RV parts stores.
