A method and apparatus according to which a connection between first and second completion joints is made up. The first and second completion joints each include a base pipe and a shunt tube disposed along the base pipe. The respective base pipes of the first and second completion joints are threadably engaged to form a pin and box connection. The shunt tube of the first completion joint is coupled to the shunt tube of the second completion joint using a jumper tube. The jumper tube is supported at a position longitudinally between the respective shunt tubes of the first and second completion joints using a first support member. In some embodiments, the first support member is longitudinally slidable along the base pipe of the first or second completion joint to the position between the respective shunt tubes of the first and second completion joints.
