ABSTRACT OF DISCLOSURE A coupling fitting for making joints in reinfocing bars or wires for structural concrete aims to provide a mechanical strength of the coupling virtually equal to the full design strength whilst providing the ability to increase the strength upto and beyond ultimate tensile strength of the rebar by the addition of resin. To that end the coupling comprises a sleeve (1) for fitting in spaced relation around adjacent portions of rebars to be joined and having positively adjustable engagers (3) threaded through the wall of the sleeve, and profiled engagers (17) to engage said portions. The engagers serve for centring the rebars and the profiling serves to provide a key preferably with both the sleeve and the rebar. It is also preferred to have the positively adjustable engagers configured to bite into the rebars. The spaced relation affords provision for introducing settable resin.
