A Sleeve For My What? (Funny Part Name)

Here's a funny part name:

Why I found it:
I slipped in the river and caught myself on the leg of my tripod. Well, the joint broke and I'm looking for the part number. Manfrotto Customer Support has given me the number of the part and I decided to see if anyone sells it. I found the part at the site above.

Well, it was funny to me.

That is funny, what would be the source for that name? I just call mine shorts. Sucks, out of stock too.

lmfao.......That has to be one of the best

Sounds like some teenager's garment, a boob tube, only lower. Or perhaps a tight-fitting miniskirt.

Kind of like a tube top but for bottoms. The tube bottom, perhaps?

Hmm! certainly open to redicule asking for one/it.

But I wonder whether it is simply an abbreviation for Assembly
