I needed to lock a toilet door from the inside the other day and there was no lock. After a bit of research I found a device in which you can use the door latches hole. Not being able to wait for shipping I improvised using a bit of kitchen hardware

Step 1: Gather the Materials

You only need two items for this and one tool. I didn't want to use one of my own forks so using a plastic one the demonstration. The rubber band is wrapped round the handle to secure it. All this can be built using a multitool

Step 2: Bend the Forks

Because every door is different you will need to size up the prongs for your own door. You want to leave enough of the fork sticking out to allow yourself to stick in th e handle when it comes especially time to lock. If the prongs are too long I bent them backwards so the sit in the hole

Step 3: Break Off the Handle

Now comes the end part. Seal off the handle so you can make the lock.

Step 4: Insert Into Lock and Secure

Once it's built. Insert the for into the door. Then close the door and insert the handle into the fork. If needed use the rubber band to stop the handle from falling out.

Congratulations you have secured a door with a fork. No need to worry about being distributed on the toilet when there are no locks to be found
