Need Interlocking Connection Info

[ShaneDoe]

I need to research the different types of Interlocking Connections that are out there. I will determine what one will be the best fit for the design I am currently working on.

I have a cylinder that will connect to another cylinder and I will need a tool less connection that will "lock" and can be removed and turned 180 and still connect and lock. Google is my friend if I could figure out the right terminology but Im not coming up with any luck.

What is the describing words I am looking for to figure out my issue?

Thanks

Something like a spring button?

Sounds like a BNC:

If you are looking to join shafts, you may want to include the word coupling in your searches.

I'm unclear if the connection must seal (is pneumatic or hydraulic ) or electrical, something else, and if it stationary, or if relative rotation from the installed position is OK .
