Of course it can detatch. You just have to undo the top strap and pull it out. See that little hole in in the middle. The strap goes through there. I am sure with more thought and engineering degree, it can be attached differently. But I tried for a while and this was the best. Underneath, put it into her nose and if a ball hit it it would push it in further. Of course it is probably going to get scratched up pretty easily, but I am thrilled that the tension of wearing the mask allows it to stay in the up position. It doesn't when the mask is off. Easy Peasy!!!
