> The audio world solved the "cables being knocked out" problem a long time ago with locking connectors (not screw-ins, so they're still quick connect) like Speak-On and XLR. The former is much more formidable.

Audio has the advantage of both ends being heavy and solid. Attaching a line that goes into a person with stitches or a balloon (urinary catheter) is done, but what happens when those get yanked forcefully is bad.
