ABSTRACT:
The coupling comprises a sleeve which receives a pair of tubular elements thereabout. One of the elements is pinned to the sleeve, and the other has a restricted, axially-movable relationship with the sleeve. Terminal ends of the tubular elements are spaced apart, in a mutually confronting relationship, and have mounted thereto circular and resilient webs or discs. The peripheries of the discs are fastened together, and the discs resiliently flex to accommodate for expansion and contraction of the tubular elements.
