A merchandise display device includes a rear cross-bar, first and second side arms, a locking pin, and a front cross-bar that is interoperable with the locking pin to secure merchandise on the display device and to secure the display device to a vertical support member. The locking pin is carried by a side arm and movable between an extended position and a retracted position. When occupying the extended position, the locking pin is adapted to engage the vertical support member to secure the merchandise display device thereto. The front cross-bar is mounted to the first and second side arms and is movable between a locked position, engaging the locking pin to prevent the locking pin from being moved out of the extended position, and an unlocked position, spaced away from the locking pin to allow movement of the locking pin out of the extended position toward the retracted position.
