What was that you said?

Got these just over 3 years ago from Raigmore - the local NHS hospital - excellent service once I'd found the departments hidey-hole in the warren. But I've had a little trouble in the last few days and today the cause was revealed: one of the tubes had split at the point where it connects. I tried cutting the split end off but can't fit tube and aid together. I'll have to go back tomorrow and see what can be done. Main problem could be parking as so many people use it as a long-term free car park and catch the bus into town. Of course I have another ear and and an aid to fit but for some reason that isn't as good.
