There were some defective cables going around a few years ago but, IIRC,
they were a bit too long at the speedo end and damaged the speedo.
I've never heard of a speedo cable breaking--they usually just kink--but
I'm sure it's possible, esp. if it got locked up inside the speedo.
Check that the cable hasn't just come loose at the OD end (though not
likely as it would be too long to go properly back into the speedo).
You can do this by futzing with the inner cable at the speedo until you
feel it go into the drive, at which point it should resist turning.
You're right, it's odd the cable would come loose at the speedo end.
But, the connector is a very fine thread and it would be easy to
cross-thread; maybe someone just got frustrated with it and jammed it on?
My gut feeling is the adapter is broken somehow, but more investigation
is warranted. The adapter should have a small copper washer acting as a
spacer for the cable; the adapter can fail if this washer is missing:
