Doorknob Lock Retaining Clip

This clip was designed to fit over a standard 50mm diameter doorknob and retain the centre locking button in the pressed/locked position.

Door handles like these are locked on the inside by pushing in a central button. This button pops out automatically if the door is opened from the inside to prevent you from locking yourself out my mistake.

Normally you can enforce the lock button to stay locked by rotating it once pressed. I practice I found this is not reliable hence I created this clip to keep it locked.
