Abstract: A locking device (10) comprising: locking members (20) to releasably engage with a locking surface (31); an actuating member (11) operatively connected to the locking members (20); hinges (201) to pivotally connect the locking device (10) to the stand (200); and a raised lip portion (23) defined on at peripheral edge of each locking member (20) to engage with the locking surface (31); wherein the actuating member (11) is pushed in an inwardly direction by a single finger movement that is translated into a lateral inwards movement of the locking members (20) causing the raised lip portions (23) to disengage with the locking surface (31) and thereby detaching the tablet personal computer (100) from the stand (200); and wherein the hinges (201) and raised lip portions (23) enable the tablet personal computer (100) to be tilted and rotated 360° relative to the stand (200).
