Abstract A clip for aiding the attachment of plasterboard to structural columns and the like comprising a box section having a spring flap formed integrally therewith. The spring flap slips onto a flange of the column and the box section provides attaching surfaces for sheet metal screws. When several clips are used the column may be encapsulated and therefore fireproofed by the plasterboard.
