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?

Reasonable quality plastic bag and a cable tie would do it just as well.
