A device for breaking solid material comprises an expansible hose element which is insertable into a hole in the solid material and has an externally substantially geometrically regular cross-section. At least at one of its ends, the hose element comprises a coupling. The device further comprises at least one expansion portion with an expansion chamber. The hose element further comprises an expansion limiter which has a varying radial distance from the outside of the hose element along the circumferential direction of the hose element.
