Claim:
A grip for retaining plural concrete reinforcing bars in a selected association comprising: a base portion including plural mating structures spaced thereabout and configured to receive the plural concrete reinforcing bars thereat in a selected association, said mating structures each including either multiple graduated engagements or a catch; and a retention portion including plural matable structures spaced thereabout each configured to engage a different one of said mating structures of said base portion, said matable structures each including one of multiple graduated engagements and a catch not found at an opposite one of said mating structures of said base portion, said retention portion having at least a first contoured reinforcing bar receiving structure positioned among said matable structures, said contoured reinforcing bar receiving structure having an internal radius selected to wrap around one of the bars received therein and create selected compression around the bar so that said retention portion grips the bar; each of said plural mating structures of said base portion variably positionable relative to and lockable with a different one of said plural matable structures of said retention portion to establish a clamping formation by selective engagement along said multiple graduated engagements with said catch so that each of the plural reinforcing bars in the association is positively gripped along a length thereof between said clamping formations.
