A two-part shelf-holder for supporting shelves on connecting members fixed around vertical posts of a sectional rack. The shelf-holder includes a fixed part fixedly connected at one end to a corner of the shelf and a movable part pivotally connected at one end to the fixed part via a vertical pivotal shaft. The fixed part is formed at another end with a curved case defining a side opening. The movable part is formed at another end with a curved cover adapted to close the side opening of the case. A free end of the case is formed of a dovetail mortise and a free end of the cover is formed of a dovetail tenon for fitly engaging with the dovetail mortise of the case. Two ends of the pivotal shaft are extended through two long holes provided on upper and lower sides of the movable part, so that the movable part could be moved linearly relative to the fixed part to engage or disengage the dovetail tenon with or from the dovetail mortise so as to close or open the two parts of the shelf-holder.
