A deck clip comprises a generally vertically extending leg; and a pair of arms extending from an upper edge of the leg. Each arm is configured for insertion into a slot of a deck board and presents an enlarged lobe. When the deck clip is screwed to a deck joist, the lobes grip the deck boards and hold them tight against the joist. The shape of the lobes increases the gripping force between the lobes and the deck boards as adjacent boards are hammered or otherwise pushed together. The lobes facilitate the gripping of the boards and help maintain the desired gap between adjacent boards for the life of the deck.
