A method is disclosed for the trenchless laying of a pipeline, the medium pipe, from a starting location to a target location. First of all a protective pipe is introduced into the ground between the starting location and the target location in a trenchless method. A medium pipe whose outside diameter is smaller than the inside diameter of the protective pipe is introduced into the protective pipe starting from the starting location and moved forward as far as the target location. The medium pipe is stabilized in its spatial position with respect to the protective pipe in the radial direction. The protective pipe is finally removed from the ground again while maintaining the spatial position of the medium pipe.
