Flashbacks can be installed in the line with clean hose ends. There are models in the market with 1/4" ends. A threaded model can be installed in the line with the fittings like this one (male or female type depending on the threaded end of the arrestor).

Of course extra joints in the line require reliable connection and inspection for leaks but technically it is not difficult at all, observing direction of the gas flow (marked with arrow on the flashbacks). For hothead flashback arresor is not necessary but since the consumption of this torch is pretty high, I think it is worth spending 30$ or so to calm down any thoughts about potential risk even if it is nearly impossible to happen.
