The locking device has a flexible plate extending therefrom and a hook extending form the bottom thereof. A second recess is defined in the top surface of the lower frame and a slot defined through the top surface so that the hook is movably engaged with the slot. The flexible plate is urged against to the second end wall when the locking device is shifted to open the cover and will return to its original position by the flexible plate.
