Presumably I should cap it, but as you can see from this photo it's
not a neat end:

The outside diameter is about 7cm.

There are flexible rubber caps for sale, e.g.

but I doubt it could be attached securely. Would a piece of some kind
of flexible rubber sheet and a jubilee clip do the trick?

I would just stuff a scrunched up plastic bag into the pipe. It not like
youre trying to block mass air flow. Alternatively, it wouldnt be that
hard to molish up a wooden plug that matched the internal diameter of the
pipe. Add a gloop of whatever sealant you have to hand if you want to make
it more airtight.
