Identification of this type of O-ring retention system using U-bolt pin 1

I'm trying to learn more about this kind of seal retention system I found, but am having no luck discovering the correct search term to learn more.

As can be observed in the attached picture, we essentially have a static radial O-ring in piston/bore type configuration. The two pieces are simply pushed together before a u-bolt-like pin is inserted into a pair of holes ensuring the two parts stay together. The two ends of the pin are not quite parallel, which provides a bit of interference that prevents the pin from sliding back out accidentally. The design also seems to allow for a very small degree of free motion between parts, such that O-ring squeeze is maintained but some slack is provided.

If you know what this kind of design is called or have other examples that you could point me towards, that would be appreciated.

It looks like a type of bayonet fitting with a u-clip retainer.

Thanks for the reply Ted. I looked that up and it seems to not quite be what I'm looking for but I appreciate the help. This design doesn't use a clocking feature to mate as a bayonet fitting seems to. The retention is entirely provided by the pin/clip. U-clip retainers might prove a fruitful thread for me to look into though.
 
What I have here is part of a Moen kitchen faucet assembly.
 
Ah, that makes sense 3DDave. It never occurred to be that this would be proprietary and to search patents. Many thanks!
