15mm pipe clips

[HiZ]

Hi,
Where can i get 15mm pipe clips to hold central heating pipes to the wall inside some plastic trunking.

Nail clips are too big, Homebase have some all in one clips, plugs and screws which are great but as i need o drill behind the pipe its difficult. The hole needs to be offset but close to the pipe.

Any ides?

Buy the ones designed to hold 2 pipes and they have the fixing in the middle, cut one side of the pipe holder off and you have a single pipe holder with an offset fixing hole.
