What it looks like before you do anything.
Push into the “push here” tab.
Now the “push here” tab is opened.
This is what the back looks like when the “push here” tab is opened. Notice in the middle there is a “pin” sticking out?
From the front, take out the strap with the spring bar.
To put the strap back on. Reattach the spring bar, sliding it through the slots on both sides.
Turn it over to the other side.
Push that “pin” in the middle to close the “push here” tab back in place.
View from the back and now the “push here” tab is back into the close position.
Turn it over and it is done!
I hope this helps.
Best ,
David
