I am looking to buy what I might call "cable ties" or even "cable
tidies".

I do not mean the usual self-locking nylon strip that is called a
cable tie.

And I do not mean the "re-usable" or "releasable" or "trigger
release" versions of the above.

I mean something more like this:

The type I am thinking of is a sort of "cable tidy" which you
might get on the mains lead of a new TV. It tends to be wider
than the nylon ties, perhaps made of high-density polythene rather
than nylon, and had more exaggerated ridges than the last picture.

Does anyone know what the correct term is for that and where I can
get them in the UK?
