It'll either be a BS951 clamp or a constant pressure roll spring. Both seem to be in use in my DNO area.
Sounds like they've converted the supply to PME and bonded the sheath, as seems to be the norm these days on a failed TN-S

the earth "strap" is a jubilee clip secured round the iron pipe coming into the house carrying the supply cables.The earth cable is secured to the pipe via this jubilee clip.It does'nt look as bad as it sounds as the pipe is quite large 50-60mm in diameter and may be too big for a normal earthing clamp.
you're sure it is an absolutely normal jubilee clip? does it look galvanised or stainless?
looks galv but defo a bog standard jubilee clip
