Transport pipe for high viscosity materials, in particular for concrete. The transport pipe includes an inner pipe ( 10 ) made of an abrasion-resistant plastic, at least one metallic joint element ( 12 ), as well as a reinforcing jacket ( 14 ) which envelops at least the internal pipe. In order to ensure a reliable and enduring joint between inner pipe and joint element, it is proposed in accordance with the invention, that the radially projecting collar of the joint element is defined by a ring-shaped end face ( 20 ) and by a thereto joined ring step ( 22 ) extending radially towards the inside of the pipe and recessed axially from the ring-shaped end face, and wherein the plastic material of the inner pipe ( 10 ) engages in the ring step ( 22 ) from the inside of the pipe.
