A locking device that may be used with display hooks is provided. The locking device includes a housing and a shell. A pivoting member is coupled to the housing. The pivoting member may be pivoted to grasp a peg or display hook in a cylindrical channel formed by the housing and the pivoting member. The shell includes a projection that is at least partially disposed within the interior of the housing and is movable in a longitudinal direction within the interior of the housing. In an unlocked position, the projection is biased away from the channel in the housing. In a locked position, the projection passes through an aperture in the pivoting member, holding the pivoting member in a stationary position relative to the housing. Further, in the locked position, the projection may secure the peg hook in the cylindrical channel formed by the housing and the pivoting member.
