ABSTRACT:
A rod and tubing connection for coupling two or more joints of tubing sections comprises a plug and a socket. The plug has a plurality of splines and the socket has a plurality of receptacles adapted to receive the plurality of splines. The plurality of splines comprises a center spline and a plurality of outer splines configured to allow intermeshing with receptacle splines in a plurality of orientations. A coupling collar is used to secure the tubing joint. The plug is connected to the socket in a four-step process of: positioning the plug and socket in close proximity, aligning the spline and the receptacle, plugging the spline into the receptacle, and then securing the plug and socket together with the coupling collar. The tubing joint may also have a conduit containing a wire for transmitting power and data between the adjoined sections of tubing.
