Garden hose coupling security

I connected two garden hoses with a Gardena coupling to create a longer water hose. I purchased the hoses from Aldi-Süd. When pulling the extended hose, the connection point of the two hoses can easily snag on a corner or other obstructions. This frequently causes the connection to detach, resulting in a high-pressure water leak. To prevent this, I designed a simple clip-on coupling lock.
