Finis Swim Snorkel newbie seeking advice

Hello all. Forum newbie here. Glad I joined as there's a wealth of info. Have a :doh:question related to the Finis Swim Snorkel I just bought. Assembly instructions say to place the tube through the head-bracket. My initial impulse is to spread the plastic on the bracket so it'll squeeze past the wide end of the tube but afraid I'll damage it. Is my fear misplaced?
