How to keep CT10 securely attached to clubs?

After one year of using CT10 sensors all works good except for one important thing, sometimes sensor fly off my club during swing. So far I have not lost any sensors but few of times I was very lucky to notice that sensor was missing after swing and finding it few yards in front of me. I have tried many ways to make sensors stay on top of my clubs mainly by applying electric tape or self amalgamated tape but this solution goes bad very quickly because tape gets damaged when pulling out and putting in clubs in my bag. 

I wonder if any of you experienced similar problem and and found good solution to it.
