A display device including: a first member including a tabletop provided with a transparent portion; a second member arranged to cooperate with the first member to define an interior space for holding an article to be viewed through the transparent portion; the first and second members are arranged to be selectively engaged together or disengaged by way of lockable operating means, the operating means being operable from a position outside the interior space; the first and second members engage together by way of two opposed retaining means; each retaining means includes a flange and a mating aperture and at least one of the flanges is movable between an engaged and a disengaged position; the operating means includes a rotary lock barrel, a locking bar, and a cam; wherein the moveable flange is disposed on the locking bar, the cam is mounted on the rotary lock barrel, and rotation of the rotary lock barrel causes rotation of the cam which in turn causes lateral movement of the locking bar to move the flange laterally to engage or disengage the flange with its respective aperture.
