LS-4 Trim Lock coming loose with stick deflection?

When new, the trim does (did) not slip on our clubs LS4s. After a few
years, they tend to do so and can be adjusted to a certain extent as
someone else described.
It can normally be adjusted so it holds with full backward stick, but
not so full forward. Luckily or coincidentally that's the safer way
round.
