What type of mains plugs for the BrewPi elements?

Folks, am about to kickstart my brewhouse setup and need some advice from those that have already been through this. I will shortly be receiving 2 pairs of 3.2kw heating elements and would like to know what plugs/sockets people have purchased to connect up to the 2 x 240V/30A circuits that I have recently had installed. My brewhouse is in France.

I looked online at the Leviton screwlock ones but they are 70-80 euros each!

Any thoughts?

Thanks

I use CEE sockets from famatel: https://www.vekto.nl/nl/contactmateriaal/cee-materiaal/cee-3-polig-16a/

The IP67 version also has a screw lock. They are a bit bulky, but if that’s not an issue they’re great!

I’m using these:
