An LED attachment ring problem

Well I bought some LED poi and they've been amazing, you get the idea. Then one day when I was practicing hyperloops the attachment ring (the part that lets the poi ball connect to the chain.) just snapped. I noticed that alot of my other poi are about to break in the same area. The ball still glows and everything, it's just the attachment piece. Is there some way to not only repair the ball but keep it from breaking again? tnx.

I've got the same poi and when I got them I saw the same problem. The attachement ring is made of the same soft material so i tought it would be a problem.
Till now i only prevent the damage, i had splitrings to attach then on the cords, but they damage the material so i got quicklinks.
If you got the same pastic material like mine, you could try glue like silicone kinds, or normal fast glue or ductape? I'm a fan of ductape, it's something everyone who performs should have in his suitcase.
