[Carl_1290]

Hi everyone, i was driving along today on the a64 when there was a loud noise from the back of the car, when i came home and looked the panel in the boot with the alarm sensors on, well the drivers side was hanging down and it had completely come off

Now how this has happened i dont know, its not been touched at all, now im wondering how can i resecure this? do i need some clips or something
