A mounting bracket assembly is configured to securely couple to a structure. The mounting bracket assembly includes a securing cradle defining a securing chamber, a pivot arm that pivotally couples to the securing cradle through a first hinge, and a locking arm that pivotally couples to the pivot arm through a second hinge. The pivot arm and the locking arm are configured to pivotally move via the first hinge and the second hinge into an over-center securing position within the securing chamber to securely lock the mounting bracket assembly to the structure.
