I've been trying to open a Telewest junction box so that I can run
another telephone point from it - I know I shouldn't but I've
fiddled around with enough telephone lines in my time in flagrant
disregard of contractual prohibitions to be fairly unconcerned about
that.

Anyway, Telewest are so sure that they don't want you to mess about
with their wiring that they use tamper-proof fixings instead of
ordinary screws to close the junction box. I've tried my Screwfix
get-into-anything set

but it doesn't work! Anyone know what sort of fixings they use?
They're some sort of six-pointed star, but the Screwfix star bits are
no good.
