The reason for metal clips is that a fireman got trapped and killed

But some what easier to break than 2.5 T&E (or bigger) after a fire
has destroyed a plastic clip, which would also have annealed the
copper and removed all the insulation. Nasty all the same.

So I take it that the hardened pin and plastic cable clip fixings are
no longer legal?
