gluing to aluminum is only to the oxide ,you need something for the glue to hold too ,like small holes , screws or a very rough surface

Do the gluing correctly on Aluminum it is up to the correct standard for structural use on Aircraft Many Aircraft have bonded structures in their construction . Without the use of small holes etc .

Thank you. Are you able to tell me more please? Where would I purchase the glue? or if I wanted to take somewhere to do repair where would you suggest please?

Epoxy glue can be purchased at most hardware stores ,and wher you could take it to would depend on who has the experience in your area .

glueing aluminium is dodgy at best as you are relying on the araldite bonding well to the "ally". My suggestion would be if there are no electrical wires in the tubing then you could try inserting a round piece of metal about 20 to 30mm
in the tubing, covering the metal insert with araldite first. Araldite is available
at Mitre 10 or Bunnings or just about any hardware store.

If you cannot use a metal insert then maybe you could drill a small hole right through the tube and use a small cable tie to pull the 2 parts together and then
layer over several applications of epoxy, letting it dry between coats.
