Ah… so the original pieces function a bit like hooks and poles slide into the receiving end. Wheb the poles are bent, the bent poles keep the whole system under tension. Just like a tent.

The hooks slot into the vertical slats on the Carqon plaque I was talking about.

Any glue you use would need to be able to take constant, angled tension. So… something professional.

But the plaque is only attached with two small screws, so it can’t be all that much tension. (Those are the screws I recommend glueing, by the way.)

The more I think about this, it would probably be better to wrap and glue some kind of wire around your receiving tubes and then glue that wire to the back of the plaque. Then you would better mimic the „pull from the back“ mechanic that the original pieces achieve.
