Where would I be able to get ....

if they look like an end feed coupling then that is what you have got and would be used as part of the plumbing process.

However I an not sure why anyone would want to cut a pipe just to solder in a coupling when they can clamp on a fitting

oops! wrong link in other post,but on saying that I'd of thought you would have had the nouse to realise the screwfix link at the right of your link to the pic.

Thanks for the links. The guy gave me a couple of straps which look like EC14 and EC16 in the link, but that the part which has the larger bolt entering it in the pictures on the screwfix page is a completely enclosed square which would slip over a 15mm copper pipe but could not be placed around a pipe that was already in situ. Hope I am making sense.

OK OK OK - cancel my last post, that's exactly what I'm looking for. Thank you George

I'm assuming that you've got the "traditional" sort of earth clamps so here's a "how to"

Thanks John, those are invaluable. Unfortunately, what the guy sold me was similar to the one shown in the first link except that the main body was not in a 'U' shape but is designed to be placed over the pipe before the tap or whatever is connected. It's a complete square where a 15mm pipe would fit into.

The second one looks very interesting though.
