An arrangement is disclosed for interlocking structural members of a building, the arrangement comprising: a) a first longitudinally extending structural member (10) defining through a substantially planar side face thereof at least one opening extending along a longitudinal axis of said side face; b) a second longitudinally extending structural member (12) having formed as part thereof, and extending longitudinally from at least one end, at least one protrusion (20) adapted for; penetration of said opening in a first position and in a first direction substantially orthogonal to the plane of said side face, interlocking of said first and second members along said first direction, and for movement along said opening into a second position; and c) a shape-defined blocking profile formed integrally on a first lip portion of said opening and adapted to prevent movement of said protrusion away from said second position, at least in the event of movement of said second member in a direction substantially orthogonal to the longitudinal axis of each of said first and second structural members. <IMAGE>
