Abstract:
1. A set of first, second, and third modular connector elements for use in assembling a wall or a building superstructure, each modular connector element comprising: a hook; means forming a catch; and means for respective connection to an end of a first, second, and third elongated hollow metal structural member for forming said wall or building superstructure; wherein each hook is complementary to each catch so that the first modular connector element is adapted for first engagement with the second modular connector element on one side of the first modular connector element and second engagement with the third modular connector element on an opposite side of the first modular connector element in such a manner that, in response to the first engagement, the catch of the second modular connector element catches the hook of the first modular connector element and, in response to the second engagement, the catch of the first modular connector element catches the hook of the third modular connector element; whereby the first modular connector element is locked between the second and third modular connector elements and said modular connector elements lock said first, second, and third hollow metal structural members together.
