1. An exhaust-gas turbocharger (1) comprising
a compressor (2);
a turbine (3); and
a bearing housing (4),
a bearing cartridge (5), arranged in the bearing housing (4) and secured against axial displacement and twisting via a single fixing element (6), which secures the bearing cartridge (5) both against axial displacement and also twisting in the bearing housing (4),
wherein the fixing element (6) has an insertion recess (8) and a holding recess (9), which merge into one another, the insertion recess (8) having a diameter (D8) which is greater than a diameter (D9) of the holding recess (9), wherein the bearing cartridge has a groove (20) with a bottom region dimensioned for mating engagement with the holding recess (9), wherein a latching lug (10) is arranged in the holding recess (9), and wherein the bearing cartridge (5) has a latching recess (11), wherein the latching lug and the latching recess have corresponding shapes with the latching lug protruding into the holding recess relative to adjacent surfaces of the holding recess, which when the bearing cartridge is seated with groove (20) in the holding recess (9) is dimensioned for being axially and rotationally constrained by the latching lug (10).
