Anyone know what this small hollow aluminum thing is? THANKS!

I've done a google image search to no avail.  

It is 4 3/8" long, the open end is 1 1/8" diameter and there's a channel inside to push this thing onto something then quarter turn to 'lock'. 
Any help is appreciated!

could be to bandage up a broken finger or toe?

Wow! Sorry the photos are so big!
I didn't even know I have hairs on my thumbs.

Looks like a spout for something?

Possibly a dibber missing its handle.

Solved! 
Fits this milk glass vintage juicer which goes to an electric mixer. Thanks everyone!
