It doesn't need to break away. It's never clipped to a d-ring while normal diving. It's there to hold it while setting up gear, while on the surface, etc. Or if you are out of air and using a buddies regulator, you can clip it off. Why would you need to rip the bolt snap off the hose? If you ever need to really get it off, slip a knife under and it will cut through easier than a big zip tie.\\
BTW, that Chinese guy's knot is total overkill. 3-4 wraps of line, do an overhand knot, flip over, square knot and melt line with lighter. Takes 5 mins.
