Compression lock

A compression lock is like a secret handshakes that can be used to keep a door closed. Let's say you want to keep your toy box closed so your little sister won't get your toys. If you push down hard on the lid with your hand, you can keep it from opening. That's kind of how a compression lock works.

In grown-up world, people use compression locks to keep things safe too. For example, a compression lock can be used on a suitcase to keep your clothes from spilling out when you travel.

Here's how it works: A compression lock has two parts, the "male" part and the "female" part. They fit together like puzzle pieces. When you press down on the "male" part with your hand, it compresses or squeezes the "female" part, which makes the lock really tight. This makes it hard for someone to pull the lock apart and get to whatever is inside. It's kind of like trying to pull two puzzle pieces apart when they don't want to come apart.

So, in summary, a compression lock is a special way to keep two things together tightly so they won't come apart easily.
