摘要：
Structural members are extruded with respective abutted edge portions having a transverse cross-sectional configuration complementarily shaped with locking tabs and undercut recesses. The tabs of a first member are interconnected by a unitary transversely extending and inwardly arcuate web. Such web is permanently deformed in a joining process by a deformation tool forcing the outwardly projecting tabs into locking engagement with the second member.
