Abstract: A security enclosure for touchscreen-type electronic media display tablets such as the Apple® Ipad® tablet. The enclosure has a rear panel that can be mounted to a display or work surface, and a front panel that can be assembled to rotate open and closed on the rear panel with a novel panel-connecting structure that requires no tools or fasteners and that is tamper-resistant. The panel-connecting structure includes a U-shaped channel with radiused connecting tabs bent from an inside edge of the front panel, and a vertical wall with radiused tab-receiving slots bent from a mating interior edge of the rear panel.
