A display device for displaying a display object includes a mounting formation for holding the display device in place, an attachment formation for attaching a display object to the display device, and a connecting member linking the mounting formation and the attachment formation. The mounting formation is configured such that it is capable of locking securely to a container or base structures. The connecting member holds the attachment formation at a position remote from the mounting formation. The attachment formation includes a control zone, and the control zone includes an entrance into which an attachment member on the display object may be inserted. The control zone further includes at least one stop formation projecting traversely across the control zone such that a part of the display object attachment member may abut against the stop formation to inhibit withdrawal of the display object attachment member through the control zone entrance.
