Replacing Diverter Valves

[SwA6]

So apparently something really simple has gotten me stumped. I am trying to replace the DVs on my 04 A6. I bought the 710s as most people would recommend and the part that is giving me the troubles is the small vacuum hoses attached to the diverter valves. I've never seen a crimp clamp before and was wondering how do I take them off without damaging them and if I do damage them, where is a good place to get some extras. I saw ECS has them but they are $2.5 a piece plus $15 shipping....... Any ideas would be great!

They are 1-time use clamps. Ive found the easiest way to cut them off is with tin-snips/shears. I use zip-ties whenever I cut off vacuum line clamps, and normal worm-drive clamps on any other sized hoses.
