A method of joining together two concrete bodies each having a concrete reinforcing bar, the method involving compressing a gripping portion of a metal sleeve on the end of the first bar with the metal sleeve also having an unpressed portion which extends beyond the bar, the unpressed portion having an internal diameter larger than the maximum cross-sectional dimension of the second of the bars, and securing an end of the second of the bars within the unpressed portion of the sleeve by means of a self-setting composition. |
