Abstract: A device for releasably retaining a downspout extension includes an elongate structural member of uniform width and thickness, selectively shaped to provide a medial top section and a pair of laterally spaced apart legs that depend downwardly from the top section. The top section can be curved, or linear with the retainer further including curved sections joining the top section and legs. The legs diverge slightly in the downward direction, and are provided with slots or other features to enhance anchoring of the retainer when the legs are inserted into the ground. The retainer is designed to overlie the downspout extension near its free end and secure the extension against the ground with its legs on opposite sides of the extension, thus to firmly secure the extension against lateral and vertical displacement.
