A theft-deterrent device includes first and second members mountable on a pair of sliding doors for activating an alarm when the doors are opened, and is particularly useful with a display cabinet containing items of merchandise and having transparent sliding doors. The alarm may be mounted on the cabinet with a tether connecting the alarm and one of the first and second members. Preferably, a magnet and a magnetically activated switch are carried by the first and second members so that when the magnet moves away from the switch, an electrical circuit opens to activate the alarm. The first member is connected to one door with a portion adjacent one side of the door and a portion extending around the end of the door. The second member is connected to the other door and is preferably a thin member which fits between the doors when opened.
