A door light fastener for releasably mounting opposing sections of a door light frame in a door, wherein a plurality of pairs of opposed cylindrical bosses extend inwardly from each of the opposing door light sections, comprises a tubular spring clip that encircles and resiliently holds each pair of bosses together. Inclined barbs in the spring clips permit bosses to be inserted into the ends of the spring clips but inhibit removal of the bosses from the spring clips. A stop projection in each spring clip prevents the bosses from being inserted more than halfway through the spring clip.
