When I was diving a traditional BC I would just throw it in one of the pockets, I never opened them during the dive so it was both secure and able to get the 'correct' water temp.
I have since switched to a BP/W and not secure it with a quick link on the plate even with heart/lungs. It's out of the way, shouldn't get caught on anything and gives an accurate depth level.
