dumb question, how to fix loose termination?

hi guys, excuse my ignorance but the banana on one of my cables is starting to come loose from the cable, i feel like if i give it a gentle tug, it's going to come right out

could anyone give me advice on how to re-secure the banana plug?

Unless you are handy with a soldering iron I'd send it back to the manufacturer and have them fix it.
Naked wire not only will fix problem but will be more superior than banana plugs. Just only slight inconvenience of connecting them.
Have to agree ...I would go bare wire..Much better contact and best solution to your problem..Just strip the ends and bend to fit ...........
