Abstract: A support assembly for attachment to a supporting surface, and preferably a vertical surface, as well as a method for assembling such a support. The assembly includes a support such as a garment hook or the like, a base on said support and a continuous retaining collar for securing the base and support to the supporting surface. The retaining collar has a base-receiving aperture smaller than the outer periphery of the base for overlapping and holding the base against the supporting surface. Although the support itself such as the garment hook is too large to allow passage of the collar thereover, assembly with the support base is accomplished by inserting only a portion of the base through the collar aperture, rotating one of the collar and base with respect to the other to pass the remainder of the base through the aperture, and seating the base against the back of the collar.
