How do I fix this broken tube, and what is it?

[Gary TVR]

I went to take the Chim out for a ride and noticed this tube hanging in the engine. It looks like the rubber piece below it is shot, and I assume it was attached there. How do I fix it, and can I drive it with it not being connected...to take it to a shop.
Thanks for any thoughts and suggestions.

Its the vacuum advance pipe to the circular metal piece in the photo. It's on the side of the distributor. The car will run without it but not properly.

Looks like it was taped together.

This should fit.
