I'm not sure if it has been disconnected or not. There are other options that are readily available that work just as well. Epoxy can be used but use a 30 minute variety. Any of the PVA glues will work like Tight Bond. I've seen some will use polyurethane (gorilla) glues but personally I don't like the foaming action as it is to easy to lock a hinge with the glue.
I've used Tight Bond on my last few builds and find it to be sufficiant.
