Sorry only just saw this..
I taped them with climbing finger tape and later duct tape, at each junction. I found occassionally they separated. My poles had been modified by a previous owner and so came apart occassionally.
It meant once they were out they were out for good. But I didn't mind using them. I started in chamonix with them, not because I needed them, just to get used to them whilst I was fresh and I just knew I'd keep putting off taking them out.
