Maybe go to a local plumbing / sewer cleaning supply company and take a look at some "sectional cable" connectors. They are pretty much inline with Pixman's bayonet mount idea. I have several sections of cable and various cutters that I use for cleaning out my sewer line at home. I can assure you, those couplers take a real beating and hold up very well. All you do is depress the spring loaded plunger on the "blade" while pushing it into the "socket" and give it a slight twist. The plunger then springs up into the slot, locking it in place. Depress the plunger and twist in the opposite direction to remove.
