Yup.  Happened on my old UrQ, fortunately right outside my house.  Once I got
down to look at it, I found it wasn't the first time it had happened.
Someone had improvised with hardware store threaded rod and coupling.
I repeated the procedure (I think it was 1/4" rod), got the adjustment wrong
the first time and snapped it again.  The second time, it worked.

>From your description, the rod to the MC doesn't have any threads.  So the
above isn't going to work exactly, but it may give a starting point.
