I've seen hose clips to that design which seemed very effective indeed.
The pressure at the contact area will be high, giving a good chance of breaking through any oxidation, etc, on the pipe.
One snag could be that they are not really re-useable as taking them off damages them. At least with the old design you can hope that the plumber will straighten them out and put them back !

Earlier on in the thread there was a statement about painted pipes.
If they were Metallic, I'd be out with the Emery tape and sanding the thing down to achieve a good connection.
Also, I would never trust plastics as a clamp used as part of an Earthing system, it's just too un-reliable.
Give me Brass or Steel any day!.
