Rod assembly and device for trenchless rehabilitation of pipelines
A rod assembly for a device for trenchless rehabilitation of pipelines includes at least two rod sections connectable to one another by a plug connection in a tension-proof manner, with at least a first one of the rod sections having an end formed with a lateral opening, and a second one of the rod sections having an end formed with a crosspiece for insertion in the lateral opening of the first rod section. Those end faces of the lateral opening and the crosspiece which are pressed against one another in response to a tensile load of the rod assembly have an arched configuration.
