Still get a 3dB loss with even a good join don't you? Best to replace.
I reckon you could repair that by slipping a couple of inches of plumbing pipe over that (whatever size the ID matches the OD best), sealing bottom and then filling the inside with epoxy resin and chopped up fibreglass. Perhaps wrapping some fibreglass tissue first depending how much space there is.
But if you need to buy stuff to do that - you'll probably be as well replacing it!
