Self-tapping connectors

[Hot'n'Cold]

Hi, Can any one tell what the above are called? They wrap round an existing hot/cold feed and bore a hole into the pipe.
I don't know what to order online. Any help appreciated

in a word cr*p (mustnt upset the mod) get a couple of tee valves and do the job properly

i shall expand on that.
After installation due to water pressure they have been known to partialy close reducing flow, when this happens you only have 1 option, yake pipe out fit t piece, so you may as well do this in the first place, it is a much better job.

Thanks for replying,
Unfortunately I can't make any alteraions to the plumbing or electrical systems as I live in rented accomodation' Only tradesmen are allowed to do the work.
I've used these connectors before and never had any trouble with them.
I'm willing to take a chance with them but still have no idea what to order.

by using them things, you are making alterations to the plumbing.

still on your head be it, go to your local diy shed they sell them in the plumbing dept
