No worries of hijacking that looks like a good way for a full one.
As for this one I honestly hadn't used the keyring at all myself as far as carrying it around but since you asked, and because I know I could easily get another, I gave it a good hard tug about half a dozen times and applied pressure pulling at it while gripping the rest of it in my hand and it didn't budge a bit. I actually figured I'd rip it for sure but honestly it doesn't even look like the threads budged a bit.
