Also, CG hooks can back release if you get a lot of slack in the rope. The manual may suggest a method for blocking the back release - make sure you remove it before winching.


If the CG hook is functioning properly (i.e. no weak springs), it
would take a LOT of slack to get a back release. So much so that
you'd be in front of the tug and probably want to release anyway.
Don't mess with the hook or you might make it malfunction completely.

Uncommanded releases are not a problem.
