ABSTRACT:
A coupling arrangement between a manifold having nipples and a solar panel having nipple receiving orifices. Each nipple is formed with a plurality of primary circumferential projections adjacent to the free forward end and a supplemental circumferential projection adjacent to the manifold. The primary projections have radial surfaces as well as surfaces inclined in a first direction while the supplemental projection has a radial surface as well as a surface inclined in the opposite direction. The coupling arrangement further includes a circumferential recess in each interior orifice of the solar collector, shaped and located for receiving its associated additional projection. Also disclosed is an improved arrangement for coupling together manifolds or grooves and recesses.
