Abstract A joint for fabricating rattan furniture particularly joining two rattan poles to form a T-shaped connection which includes forming a saddle at the end of one pole, forming an axial hole in said one pole, locating an internally screw-threaded sleeve in the hole, fixing the sleeve in the hole by passing a pin through the pole and the sleeve, passing a bolt through a diametrically disposed hole in the other pole and screwing the bolt into the sleeve to seat the other pole on the saddle.
