Abstract
An overlapping or nesting connector is provided for connecting adjacent edge restraint sections. The edge restraint includes a substantially upright section and a base section, and may include braces extending between the upright section and the base section. The connector may be formed integrally with or separate from the edge restraint sections, and includes at least an upper wall, and optionally lateral walls and/or a rear wall. The upper wall may define an opening for a spike, and the brace or coupling structure with which the connector overlaps may define a corresponding opening for receiving the spike, which openings are aligned when the connector overlaps the brace. After adjacent edge restraints have been connected via the overlapping connector/brace, the spike is driven through the aligned openings into the underlying surface to provide a strong connection between the adjacent edge restraints and between the edge restraints and the underlying surface.
