The bad economics of replacing a broken tent pole , any repair hacks?

Folks,

Have a few tents that have started to feel their age. Have those fiberglass poles and they have broken off in the ferrule or sleeve or whatever you call it.

Had a local shop that would sell me single poles of various sizes which was great before as it was only a couple of euro a pole. Shop is gone now unfortunately.

Looking online amazon etc the poles come in sets and with postage etc I might as well just get a new tent.

But feels like a shame to toss a good tent because one fiberglass pole is snapped.

I see these sleeves you can get , not sure if they will help me as my breaks are at the point where the pole goes into the receptor on the next pole.

Any hacks to fix?
