Spec me: Flexible tubing

[Russinating]

I'm after some white flexible tubing that I can slit down one side to wrap round and hide cables. I know exactly what I want but B&Q's website is as hard to find anything on as their actual stores, so could someone point me in the direction of the correct name and/or the usual usage for these?

Thanks .

cable sleeve
spiral cable
cable wrap

etc google if your friend "cable tubing" as a search term seems to work well
