Was it all elastic or have a metal connection? Watch her closely for a few days for impacted crop issue. Check her crop before she eats anything for the next few mornings and make sure it is small and empty. If she starts acting ill or her crop is not empty in the morning, then post under emergencies.
I agree with sunflour that you should make sure her crop doesn't get impacted and post under emergencies if it gets worse. We had a hen named Dottie who got an impacted crop most likely from grass and didn't make it. Not trying to worry you, it's just good to be careful.
I also lost one of my hens to a lower intestinal impaction and don't want to get you really worried, just want you to watch yours closely. Thought mine had an impacted crop but the impaction was lower down.
