The security device of this invention comprises a transparent panel normally locked edgewise upright in the plane of front edges of a pair of vertically spaced shelves of a selfservice rack, blocking forward removal of all but the lowermost one or a predetermined few of a stack of like articles on the lower one of those shelves. At its top edge the panel has a link connection with the front edge of the upper of those shelves. Its lower edge portion is received in an upwardly opening groove in a fixed bracket, and the bottom of that groove so supports the panel that the link connection cooperates with resilience of the panel and bracket to provide a snap toggle action between locked and unlocked or releasing conditions. From the releasing condition the panel can be raised edgewise out of the groove and swung up to an inverted position and hooked there, permitting free access to the space between the shelves.
