An improved clamp and method for forming a [www.rebar-coupler.com rebar splices] in a vertical reinforced concrete body. A split-sleeve type clamp with contraction means for firmly closing it around the engaged end portions of a dowel rebar and extension rebar has a location tab struck from a central portion of the sleeve, projecting upwardly and inwardly at an acute angle to engage the upper edge of a dowel rebar onto which the sleeve is driven. The clamps shown therein have performed most satisfactorily in use, both in terms of strength and durability. The present invention is directed to a further improved clamp and a new method of installing the same which is designed to minimize and simplify the effort and manpower required to form rebar splices in a vertical concrete structure, such as a column or wall.
