Abstract: This invention relates to wall siding assemblies, particularly to horizontal siding panels and to improved clip means for connecting same to the sides of a building structure. Each siding panel has two elongated recesses or grooves on its backface near the bottom edge of the panel, one recess being nearer the bottom end than the other, with a resilient clip having opposite end portions located in the respective recesses such that the clip is retained in engagement with the panel. The clip has a support leg extending therefrom. Each successive panel is assembled on top of a lower panel already secured to the wall, by positioning the support leg of the clip in engagement with the upper edge of the lower panel, with the lower portion of the upper panel overlapping the upper edge of the lower panel. The upper edge of the newly installed panel is then secured to the wall, for example, by nailing. The clips are easily assembled with the panels, and installation is a very simple matter.
