Wheel clamp / parking brake Yeep Me 80n start scooter

Bought a cheap little scooter to take with me on public transport. Pretty happy with it, but ran into the issue that you couldn't lock the front wheel. And sometimes I need to be able to place the scooter down vertically without it running away from me.

The little round peg goes into one of the round holes on the front wheel. Place the springy bit towards the axle holder. Then you just push the scooter backwards until the spring goes past the other end of the holder and you hear it snap in place. To release, press down on the spring bit and push the scooter forward.
