Pipe connection 1

In disconnected state the fluid can not flow out due to the contact of yellow balls with green and popcorn parts under spring forces.
In connected state brown part pushes the balls, thus prevent the above mentioned contact and the fluid flows through holes on the brown part.
Most parts are cut off half for easy understanding.
