yep, easy to repair.....................
1.Get a hacksaw and cut off the two broken ends so both bits are nice and clean and not splintery
2. Then feed the male end (top end) through the female end (of the bottom section) and pull it as tight as you can so it is wedged in.
3. tape join up with Duck tape.
Hope that is clear. Its hard to describe what I mean by point 2 :

but let me know if you get stuck.
I have repaired 3 sections and they work fine and never had a problem again although the repaired sections are a bit shorter now!
