Yup! Basically safety spears are to stop people blowing their heads off in pub cellars (also act as a form of tamper evidence).
you can cut the tab bit off a safety one to make it 'unsafe' :wha: .
When you are putting the coupler on you are tightening the thread, when you are taking it off you are loosening but usually people wont use much force removing them and besides there is a fairly long thread and you hear the hiss before much chance that you get decapitated.
