Welcome back Mark and thanks for the pic! The tab can be used for securing the EZ Coupler 4-in-1 Threaded RV Sewer Adapter item # F02-3112CL. That's actually a new feature they've added. It can be used for hanging the adapter up or tying the coupler down to the dumping station if it doesn't have threads. Some people also secure their end cap to it with some rope or thread.

Do you plan on storing the adapter with the sewer hose or removing it?

Thanks Jarred. I just have a little camper van. I’m storing the sewer hose in the storage tube under the van. Unfortunately, that tube will not accommodate the adapter so I do take that off. I store that adapter piece in a leakproof container inside my van.

@MarkK You're welcome! Ok, I was curious if you might be able to squeeze that adapter in. Most can't and use the same method you're planning on doing.

@JerredH Now I’m curious. What options are available or what do other class b camper van folks do to store that adapter? If I can store it under the van that opens up space inside.

@Markk From smaller Class B camper's like yours to the biggest Toy Haulers most people store it inside a storage compartment. The bend in the adapter doesn't like to fit in the tubes for the sewer hoses. I always think that someone should make a folding one but then remember what's going through it and how cleaning out those joints wouldn't be easy.

I think the small tab you’re asking about is simply for the retailer to hang them from the sales rack. I trimmed mine off when I got it. These elbows are awesome tho, they’re one piece, instead of having the 4 little tiny locking tabs that inevitably break off while trying to tighten your hose. And they are also so incredibly clear that you can actually see how clean or dirty your tank is by the water coming out. Most “clear” elbows are just frosted looking.
