Abstract
A splicing device for concrete structural members includes two mating connectors positioned in axial alignment adjacent to each other that are interlocked by a key inserted through a keyway provided in the sidewalls of the connectors. Prestressing strands in the structural members to be spliced are fastened to the connectors by inserting them into axial holes located in the ends opposite the mating ends of the connectors, and thereafter wedging the strands within frustum-shaped cavities forming part of the holes, by means of frustum-shaped segments, or feathers, forced against the elements within the cavities. Apparatus and a method for installing the splicing device is also described.
