Compression Ring in the picture. The "body" would be the valve you'll be replacing.I'll get some snaps of the setup for you tomorrow. The current valve has a knurled knob to turn. That's where the problem seems to be, as when I applied some plumber's tape in a bid to stem the leak, I got a jet of water to the eye. I'm looking at something similar on the screwfix website as a possible replacement.
P.S. What are olives? Other than the green things you put in martinis LOL
