A clip for attaching composite structural trusses to lateral bracing members consisting briefly of an elongated metal member formed with a pin opening at one end for attachment to the metal truss connecting pin and a flat surface adapted for abutment with the edge face of the wood truss chord, and the other end of the clip is formed with fastener openings for receiving fasteners such as nails, screws or bolts therethrough for attachment to the wood brace member. The surface adjacent said fastener openings is flat for abutment with the side face of the wood brace.

DETAILED DESCRIPTION The gist of the present invention is the use of a pair of light metal clips, each connected to opposite ends of the metal truss connector pin and to the lateral brace.
By connecting the clips to the outboard ends of the metal pin, the moment arm between the points of connection of the clips is much greater than the momemt arm between the metal webs where the overturning moment originates and hence a much lighter clip may be used.
By connecting the clips directly to the metal pin, the force moments are never carried into the wood chord which has little resistance to such forces.
For example, in the Troutner truss U.
S.
Pat.
No.
3,137,899, supra, the moment forces as shown in FIG.
4 exert a downward force on one side of the pin 9 and an upward force on the other side of the pin 9 which results in a tendency of the pin to cause the wood chord to split.
The clip of the present invention is less expensive to manufacture than some of the prior art straps, less metal is used, no additional fasteners are used to attach the clip to the wood truss chord which cause weakening of the chord.
