Some years ago I had a back release on the belly hook of my Pik-20D while
being towed in Gap Tallard France. I was still pretty low when it happened
over unlandable terrain in mountanous area (near the Petite Céuse). Luckily
enough I could just make it back to the airfield.
Since then I use a small piece of spongie rubber between the outer ring of
the Tost hook and the fuselage at the back side of the ring. In this way the
outer ring can still move backwards when necessary, but not very easily
anymore. I have had no back release problems since then. I use it also on my
later gliders.

As one who has had a back release 50 miles from home, over the desolate
terrain of central Nevada, just after sunset, I can relate to that!
