I had to replace mine, this little piece of plain looking plastic looks like the letter 'T' used in aquarium installations. but 10 times more expensive. I figured I could use some sort of fastener to hold it in place, like the Red Green Fix. Long story short, it didn't work and the hose shifted a bit over the course of a couple of hours causing it to leak and form around the back half of the oven. repair cheaply.
