I believe it is a Plasson "Line 7 Universal coupling" #77010 that you are after.
See here and go to the "online catalogue". Its in the Line 7 section.

Keego - have a look will ya? See if we're on about one and the same...

Sad isn't it after 17 years digging them I still have to look down it when I pass one

If you were NWW DLO then you've probably seen the inside of more holes since you left

That be the one, & it will work on galvanised as I've used one on it before.
BB, yes I was NWW DLO & the biggest hole I've seen since I left was the one the b*st*rds drove me to when they contracted us out, took a good few years to get out of it as well.
Still in the long run it worked out OK.
