Need help to identify name and type of this nut

[Heng Li]

Hello everyone,
I am looking for one special type of nut (see image) for weeks without success. It is used to connect threaded part and syringe needle. This thing is driving me nuts. Is there any place to get similar ones or what is the exact name of nut in this shape?

Thanks!

Welcome to the PF.

What do you mean by syringe needle? Is this for a medical application?

I think this is what you mean. https://www.google.com/#q=luer+lock

It is used to connect threaded part and syringe needle.

I've needed a lot of injections and IV recently and none looked like your photo. They all looked like the luer lock in post #3 which seems slightly different.

Is the one in your photo broken?

Would this do?
