My Light Stand SLS-LS96HA from Tokina was loose in one of the stages.
Step 1: Removed the Broken Stage Lock.
By removing the small screw with an allen tool i realized that the plastic lock was cracked.
Step 2: Made a New Lock of Instamorph
I molded a new lock of instamorph pressing a rectangular piece of warm instamorph in the tripod to made a round face on it.
Cuted a hole in the center with a swissarmy and turned the screw into it to make the thread.
Step 3: Reinstall the Lock
Reinstalled the new lock into place.
