Abstract: A clip is disclosed which can secure a corner of a box formed from a blank of suitable material of which the margin is folded to constitute a peripheral wall for the box, the ends of the two adjacent wall portions overlapping at each of the corners of the box and therefore requiring a securing device at each corner such as the clip disclosed herein if the box is not to collapse. The clip is in the form of a bifurcated member of resilient but self supporting material, preferably plastics material such as polyethylene or polyurethane, the two furcations being connected by a head portion. One furcation is shorter than the other and is adapted to fit inside and along the corner of the box, whilst the other longer furcation is adapted to extend along and outside of the corner of the box with its free end terminating in a foot portion which is adapted to accommodate the corner of the base of the box.
