End of spool securing?

What’s the recommended method for securing the end of the filament where it meets the spool core? I ran into a problem with a spool that had some filament kinked into the core of the spool and the AMS did not want to stop using that spool and start using another (via auto-fill). The spool was too light to allow rewinding, but the AMS couldn’t yank the end of the filament off of it in order to feed it all the way into the extruder.

So if I’m going to re-spool filament, how should I go about making sure this is less likely to happen?

I use these for respooling on bambu spools, I’ve made the pull-out in the centre so they work on both the AMS and the Lite (which is offset).
