## Abstract

System for fixation of shelf accessories to a shelf, the system comprising; —an elongate front fixation device (120, 220, 320, 420) having a longitudinal direction and being arranged to be fixed to a shelf (10), at or adjacent and in parallel with a front edge (11) of said shelf. The fixation device comprises at least one channel wall (123, 223, 323, 423) defining a longitudinally extending, open engagement channel (124, 224, 324, 424). At least one shelf accessory (140, 240, 340, 440, 640) is arranged to be supported on an upper surface of the shelf and comprising an engagement member (150, 250, 350, 450, 650) arranged to be brought into engagement with said channel wall, for fixation of the shelf accessory to the front fixation device and the shelf. The shelf accessory comprises a resilient member (158, 258, 358, 458, 441a, 600) arranged to press the engagement member into an engaged position at which the engagement member is in engagement with the channel wall and to allow the engagement member to be brought to a disengaged position at which the engagement member is disengaged from the channel wall by deformation of the resilient member. The resilient member is arranged to contact the front fixation device both in the engaged position and in the disengaged position of the engagement member.
