buy some superglue.....
No, really, been there, bought the tee-shirt....
Slide the top part of the broken section up through the fatter lower section.
This should 'bite' near the break, providing you have a couple of inches where there is good contact, this repair will work perfectly.
Slide the sections apart, smear superglue over a couple of inches of the thinner part of the broken section right up near where it has broken.
Shoot the thinner section back up through the other piece, when it grips (don't pull it through too far!) twist the pieces a couple of times to smear the superglue against the other part of the pole section.
It will 'bite' very quickly, wrap some duck tape or similar around the break (splinters).
Try it, what have you got to lose?
It'll be ready for use within minutes.
I'm still using my 'snapped' section every day.
