What the heck are these compression fittings?!

Beneteau M500 Bandon, OR
Hi all! I'm replacing some leaky freshwater fittings on my 1990 Beneteau. Our entire freshwater manifold and some intake seacocks have these black plasticky compression fittings. They have a cone, a hoop with a slit, and an o-ring inside. We cannot figure out what the pipe thread is for us to replace these. The previous owner thinks that they might be European, but had no insight into the make or thread.

Does anyone know what these are? If so, where can we get replacements?

THANK YOU! Been searching the web to no avail!
