I'd bet the crash couldn't directly loosen the cable - too low-speed, with an extremely large "crumple zone". And connectors designed for shipboard use (tossed about by storm waves & such) might be pretty resistant to jarring loose. But what the crew might have done with that connection, right after the crash and plausibly in an "OMG!" panic...that'd be the huge question, in my mind.
