The disclosure is of a clip, constructed of plastics material, adapted to secure together, in a stack, a number of berry box trays, all of the general type disclosed in my prior U.S. Pat. No. 3,750,936, the clips being adapted to operate at certain times as a handle, and at others to coact with a paperboard dust cover sheet to releasably bind the latter in a secure manner onto the top tray of a stack of such trays.
