Abstract: A clip for installing panels of siding to an underlying structure is disclosed. The clip has an upper tab portion that extends downwardly to a forked neck. The upper tab portion is adapted to receive a fastener. A front portion and a rear portion extend downwardly from the forked neck. The clearance between the front portion and the rear portion is sized to receive a nail hem of the panel of siding. The rear portion includes a forwardly protruding lip, and the forward portion includes a rearwardly turned curved hook. Both the forwardly protruding lip and the rearwardly turned curved hook engage an uppermost fold in the panel of siding just below the nail hem. This configuration allows the clip of the present invention to simply and quickly snap over the top edge of the panel at any desired location along the length of the panel, and eliminates the need to install individual clips one at a time from one end or the other of the panel.
