Between the first and second pipes and between the second and third pipes there are flexible bellows units and a pair of links on opposite sides of the second pipe are connected at their ends through spherical bearings to the first and third pipes so as to permit relative movement between the first and third pipes in two mutually normal directions which are also normal to the longitudinal axes of the links.
