Climaflex do clips to hold the edges together and they are easy to apply, but they are overpriced and I couldn't help feeling that gaps would open up with time. I used a few of the clips (about 3/m) and taped the joints with high quality duct tape. The tape I have used in the past appeared to have a thermoset adhesive which will not slip or loosen with time/heat. The surface of your insulation should be cool anyway, or it's not doing it's job :-).
btw, I don't class 'duck' tape (worst I have ever used) or other shed stuff as high quality, chose one from a back street plumbers' merchant or other quality source. I'd suggest BES, but they now charge postage on small orders :-/

Yeah, that's a cool idea. I still had to use the tape tho' as I was using plastic pipe & I wanted to keep it all together on the bends.

I avoid splitting it whenever possible by threading it onto the pipe before connecting both ends up. If you are soldering the ends, then you will end up having to leave a gap which you fill afterwards, but I do this by inserting a short split piece somewhere on a straight run, and sliding the rest along so there aren't split pieces on bends or even at the ends of runs.
I doubt any tape will last anywhere near the lifetime of the pipework.

I don't know if I'm breaking any rules, but I use that garden wire that comes on a reel with cutter and just twists together.
Easy to fix, easy and clean ti disembrangle, and dirt cheap, specially at Poundstretcher
