ABSTRACT:
A scaffold plank correction arrangement comprises a pair of identical connectors, each having a horizontal flat portion attached to a plank and a folded-down tongue portion integrally formed therewith. A transverse slit is provided in the flat portion of each connector, which slit extends parallelly to the common boundary between the flat portion and the tongue. When the connectors are placed in an overlapping relationship, the tongue of one connector protrudes through the slit in the other connector whereby a direct connection is formed between the ends of two adjacent planks (FIG. 2).
