ABSTRACT:
A storage rack having a column with a front flange and side flanges engageable by a clip mounted at one end of a load support is provided with an improved locking assembly for releasably fastening the load support clip to the column. The locking assembly includes an L-shaped connector member comprising a threaded shank extending through a hole in the clip and through one of a row of apertures in the front flange of the column and a lug engaged inside the column. A nut threadedly engaged with the shank has an integral annular flange which engages the front of the clip when the lug engages the rear of the front flange of the column. The lug is bent at less than an orthogonal included angle with respect to the shank from a material which affords elastic flexure of the lug relative to the shank when the nut is tightened to provide a locking action. The lug is dimensioned lengthwise so as to engage the side flange of the column for cooperating therewith to prevent rotation of the shank when the nut is tightened and loosened.
