ABSTRACT OF THE DISCLOSURE A splice sleeve for receiving and connecting adjoining ends of a pair of reinforcing bars or rods in which the sleeve includes a rigid shell having a cylindrical external surface and an internal surface with ridges constructed to provide a wedging action and compression of grouting intro- duced into the shell. In one embodiment, the shell includes an internal surface which tapers inwardly toward the ends of the shell. In another embodiment, the shell has a cylindrical internal surface with ridges which increase in height from the centermost ridges to the outer ridges. In a further embodiment, the shell has a cylindrical external and internal surface for approximately one-half of its length with the other half of its length being smoothly tapered and provided with external longitudinal flanges and both end portions of the shell have internal ridges with the ridges in the cylindrical portion progressively increasing in radial extent from the inner ridge to the outer ridge and the ridges in the tapering portion of the shell being of constant radial extent. In a still further embodiment, the shell is substantially cylindrical throughout its length with only one tip end por- tion of the shell being sharply tapered inwardly with the wall thickness of the shell being constant and the ridges being constructed to provide a wedging and compression action at each end of the sleeve.
