A clamping screw has simply broken. This screw is plastic; impossible to "pick up" or repair. We tried the super glue (much) but the forces applied are too large, and it ended up fart - what one would * really * not when you're trying to baby swim; because the bath could tip once!
I spent the big white string around the table to do a repair "home" and suddenly it's solid foolproof; far more than their plastic screws. So we use and we are very happy.
But I advise against anyone who is not ready to patch it with twine.
