I had exactly the same problem when I changed mine and yeah a pair of snips will do the job or if you're careful a dremmel type jobbie will do nicely. Replace with Jubilee clips as previously said. I found with mine that the top hose was in good condition and I just pulled the old one off (clip and all) and pushed it onto the new DV without having to remove / replace the clip. Good job too as I couldn't find a jubilee clip small enough to go into the recess at the top. A year and a half later and its still going strong.
