Earth clamp for 50mm Earth cable

[Lagentium]

Could anyone recommend a bonding clamp that accepts a 50mm bonding cable please for a 3 inch diameter gas pipe? Welding a flag onto it is sadly not an option, I also have to get a 50mm Earth onto a 40mm water pipe, any idea guys?
Cheers

Showing my ignorance again, but those look like big jubilee clips...
I love 'em! Used to use them to clamp the asbestos rope round the exhaust on our powerboat
