Abstract: A securing assembly for securing together a pair of adjacent round tubular frame members each having a pair of co-aligned apertures includes a elongated fastener, having an enlarged diameter central portion and reduced diameter end portions each of which is provided with a plurality of retaining projections. The enlarged central portion is adopted to fit in the two inner apertures and a pair of cap members having internal blind bores are fitted over the retaining projections and are disposed in the outer apertures. The retaining projections are each comprised of a continuous helical ridge of angular shape sloped toward the central portion and the internal blind bore of each cap member may have a plurality of unthreaded retaining ribs.

Abstract: This invention relates to a spa which may be used in an in-ground or above ground swimming pool or other liquid containing structure.The spa includes a frame capable of supporting a person or persons and comprising one or more frame members having a plurality of apertures or perforations. There is also included conveying means connectable to a liquid source such as the outlet pipe of a swimming pool for conveying liquid to the apertures or perforations included in the spa frame whereby liquid may be expelled under pressure of a person or persons supported by the frame.Suitably there is also included aerating means associated with the conveying means for aerating liquid before being expelled from the apertures or perforations in the spa frame.
