I think there is only one type of lead/connector for the 230v/240v leads - certainly I use them all interchangeably and I have pretty much a full range of stuff.
The green lead is much nicer material than the black ones - firmer but slicker, sort of silicone rubber - I recently bought a green lead which I leave permanently plugged into the CT26. The green lead only comes with a euro two pin plug - I was going to snip it off and replace it with a UK 3 pin plug, but then decided to get a euro plug module for the CT26 - all from Nuts & Bolts.
Hope that helps.
Cheers
Phil's post crossed with mine, but they are consistent I think
