Abstract: A system for assembly between a sheet of glass including a countersunk hole on each of its sides and another sheet of glass also including a countersunk hole on each of its sides, each countersunk hole being designed respectively to take first and second connecting pieces, each of the first and second connecting pieces being provided with a bore. The system also includes a connecting core connecting with the first and second connecting pieces. The core includes first and second parts. The first part of the core mates with the surface of the bore of the first connecting piece on which it exerts a force roughly parallel to the axis of the hole and the second part of the core fits into the bore made in the second connecting piece therein to react to the force.

Abstract: A structural clip includes two connecting legs extending from a resilient spring means with a securing loop at the end of each leg. The angles defined by the legs and by each leg and the spring means when the securing loops are connected to a bottom support member secure that member and a contacting top support member in any spatial relationship one to the other without auxiliary tools. An embodiment useful over a range of support member diameters for perpendicular or parallel reinforcement member alignment, and a method for using the clip also are disclosed.
