The actual Bonding cable should be connected to the left pipe clamp.

Not what the Regulations or Gas Companies state but that is the extraneous-conductive-part - as too is the other pipe if it reenters the ground.

Can't see if the green cable is also connected. Where does it go?

Geoff, the original green smaller cable goes to the main earthing terminal. I am surprised that it went to the gas supply pipe not the pipe on the consumer's side of the meter, i.e. the copper pipes at the top of the picture.
