Simple question: Should the braid be connected to anything? The back of
the wall plate looks like a connector for the central copper wire plus a
clamp for the cable. does the braided sheathing need to be connected
through to the telly???

The clamp goes onto the braid, ie the outer sheath has to be removed.
Make sure the braid doesn't short onto the central solid wire.

No!

Strip back the outer sheath then fold the braid back over the
sheath - you may have to partially or totally unravel it -
and place both the braid AND sheath together under the clamp.

If the cable also has a copper foil screen, rather than a
bonded aluminium one, tear it off so that it can't get in the
wrong place.

The clamp performs two function, one physical and one
electrical.

Is it ... IYHO of course!

The cable is not subject to mechanical stress as it's behind the wall plate.

So, between the faceplate being off and back in place, there is no
chance any strain could be put on the inner conductor (if the clamp
wasn't providing any mechanical support)?

Or if someone pulls the cable from the other end ... ?

What you meant was in 'harry's world' (... Imagine how sad / sick a
place that would be if it was a Theme Park ...) you couldn't imagine
any circumstances where making sure the mechanical clamp was as good
as possible would be a 'good idea'?


So why don't they have a cable grip on the incomer(s) of a 13a socket?

The consequences of an aerial cable coming loose are trivial anyway.
