The plastic cover should have a lip that catches on the plug so it wont fall out. I have never had mine come loose.
Cover should be spring loaded to snap shut, plug should have a tab on top. Lip on cover locks tab in place and secures plug. If both parts are well maintained the plug should be secure.
A couple times I never got the plug pushed in far enough to let the lid catch the back of the plug, was just sitting on the very edge of the tab ,and not going down to secure the plug. Caught my mistake after a couple times, that could be the OP's problem not getting it pushed in far enough to allow the spring loaded lid to catch the plug
