Edward,
Use a simple loop and pin release on both. Yes you can purchase cam releases for the sailplane and machined releases for the tug but for practicality a simple release is still the most positive.

Heres a good page for a tow release.

It's in German but can be translated in google translate.

Hi scale soaring has some articles on both. There are several articles on current mechanisms.
