Forget a permanent fix with an ABS coupler. Go to a large hardware store and buy a Fernco (it’s a Hubless connector made out of rubber with full circle clamps at each end), some areas of the USA call them CT’s also.
It looks like a piece of hose with hose clamps. Place it on the pipe and tighten it in place. It’s a drain line so you really don’t have to worry about pressure, but more importantly, if it clogs again, you have access to clean the pipe.
