Canon 100-400 Mk2 Zoom Adjustment Ring (1 Viewer)

A question for anyone who has this lens, when the ring is set to fully tight should it be locked so the zoom can't be moved or just tight on the resistance?
When I bought the lens a few weeks ago I may be wrong, but I'm sure the ring would lock tight but now in the fully tight position it can still be moved
The lens doesn't creep but I'm concerned that if it has loosened off in a short space of time will it ultimately loose off altogether

Has anyone had the same experience?
