Best way to clean S/S type keg connectors

[Natdene]

After my JG fittings broke I'm trying to get some kegs connected and I was given some of these connectors. I have never used them before so what's the best way to clean them? I can't work out how to pull them apart. Currently have soaking in Nappisan, then going to give a soak in sanitiser

Cheers will do, can you pull them apart?

Looks to me as if you could,I see the tail of the connector has 2 nuts at the end so maybe the tail could be unscrewed from the main body.
Could and maybe...
