    Abstract: A clip for holding a downspout lateral in the tipped up position has a C-shaped body constructed of transparent, resilient plastic. The clip is resiliently snapped onto a downspout some distance above where a lateral joins the downspout.

The lateral is tilted upwardly until the upper edge of the lateral rests against the clip then the clip is slid down slightly until the lip engages the upper edge of the lateral and thereby retains it.
