Ah, OK. I've got several of them, including the double version (terrible, because you can' breath normally). To make them "fit&sit" you warm them up in a hot water, then place on the teeth and manually "squeeze" them in place. That's it. They usually do not fall out, but also there is practically nothing to hold them in place.
I have a locking gag. Lockable strap that is.
When i put it on, i always lower my head as far down as possible. Then put the strap on as tight as it can. Lock it and done. If you tilt your head back up, my experience is, the strap sits even more tight! Sometimes even to much 😉
If the gag is not too long, too big, too stiff and/or tightened on the verge of breaking/dislocating the jaw, I still think it can be removed, provided your hands are free. Hence the topic 😊

In this case, it's more about discovering anomalies from a far distance. I also would prefer to avoid head-harnesses, but from a far distance they will be less noticeable or suspicious, than a "black head" with no face features.
That's a very good suggestion! But ... the question remains - how to make a gag inescapably locking? 😁
