The invention relates to a casing for a geothermal probe for obtaining geothermal energy, in particular deep geothermal energy, wherein thermal energy is transported by means of a preferably liquid heat transfer medium from a deep area in an upper region of the geothermal probe, with an outer conveyor pipe (13) made of a metal and with an inner conveyor tube (15) inside the outer conveyor tube (13) made of a heat-insulating plastic, which consists of a plurality of inner tube sections (15a), wherein the inner conveyor tube (15) at two or more axial positions of the casing (5) by means a load transfer device (23) for introducing axial forces acting on the inner delivery pipe (15) onto the outer delivery pipe (13) is connected to the outer delivery pipe (13). According to the invention, the inner tube sections (15a) are coupled at coupling points between each two immediately adjacent ends of the inner tube sections (15a) in axial sections between two load transmission devices (23). In addition, in each section at least at a coupling point between one of the two load transfer devices (23) and the immediately adjacent end of the respective inner tube section (15a) is given a coupling, wherein the coupling at the coupling points without a material connection generated by axial compressive forces or at least or at least supported becomes.
