Alex is quite right, that will work a treat, depends on the length of the split and the amount of damage though.
Instead of superglue you can also use epoxy glue, it's a little more permanent...trust me...I know!!!!
If the amount of splitting is a little too much to be able to risk cutting, go to your local motor factor supplier, Halfords and the like, and get a fibreglass repair kit.
Sand the damaged section, wrap with fibrglass matting and follow instructions on the pack.
It will make the section a little heavier, but as a DIY solution it is a strong and sturdy repair....sigh, I know these things!
No doubt taking it to get it professionally repaired is the best option, but for myself I couldn't do without the pole section for the time it would have taken to get repaired.
