I mean, that’s not the worst suggestion? Drilling a hole and adding a screw could work. Now, whether that screw will start rusting and shedding rust shavings/dust into your food after a few washes is a different matter.

Honestly though, OP, it’s best to just replace. If it’s got sentimental value for whatever reason, you could try crimping the end of the tube or do go the drilling route and use a non-metallic holding mechanism (e.g. plastic screws or even a small circular plastic rod with an end that flares out after exiting the other side so it stays in place).
