It must be a single continuous cable, no Henley blocks or similar as
they are points where unmetered electricity can be taken from.

Why can't they solder/weld (I'm not sure that soldering is still the
right term given the size of the cables!) with a sleeve over the top (and
put it in a box if they're worried about mechanical strain relief - but
the point is it would end up as a solid joint)?

Surely that would be no more and no less tamper-proof than the actual
cables either side of the join?
