but these can be easily slackened off
10 June 2018
Works for making your case more secure for air travel, but these can be easily slackened off.
So the answer is to buy a belt grommet tool set for about £6 or less, then fit it to your case and lock it, then once your happy with the fit fit the grommets to the strap on your case. You won't be able to use it for a different sized case after that, but nobody will remove it without cutting it off.
For me it was just to help keep the contents in the case and less as a security feature.
