Ah I see. Totally misinterpreted what you meant by falling apart. I thought you meant that the screwbar was removable without you unscrewing it.
A dab of loctite would be perfect. Not sure which one to suggest though, would have to be whatever their most temporary one is. Maybe somebody else on here knows more about loctite!
I've used 222 (purple) on bracelet screws before, so still have a lot of a bottle in a drawer - I'm Bromley way-ish if you're anywhere remotely close but probably more time/cost efficient to buy.
