A planet carrier for a speed reducer of a turbomachine, this planet carrier having a main axis X and comprising: - a cage carrier comprising an annular row of axial fingers about the axis X, which comprises first connection elements, and - a cage comprising an internal cavity configured to contain a central sun gear of axis X of rotation and an annular row of planet gears arranged around the axis X and meshed with said sun gear as well as with a ring gear intended to surround the cage, the cage comprising at its periphery housings and second connection elements which are mounted in said housings and which cooperate with the first connection elements to form connections between the cage carrier and the cage, said connections having at least one degree of freedom, the cage comprising two shells (220a, 220b) which are axially assembled to each other, said first or second connection elements comprising broaches oriented radially with respect to said axis X and passing through radial orifices (220a1, 220a2, 220b1, 220b2) of said shells (220a, 220b), characterised in that each of the shells (220a, 220b) comprises tabs (294, 295) evenly distributed about the axis X and being at least partly superimposed in radial direction with the tabs (294, 295) of the other shell (220a, 220b), the tabs (294, 295) comprising one or two orifices (220a1, 220a2, 220b1, 220b2) for mounting each of the broaches. - a cage carrier comprising an annular row of axial fingers about the axis X, which comprises first connection elements, and - a cage comprising an internal cavity configured to contain a central sun gear of axis X of rotation and an annular row of planet gears arranged around the axis X and meshed with said sun gear as well as with a ring gear intended to surround the cage, the cage comprising at its periphery housings and second connection elements which are mounted in said housings and which cooperate with the first connection elements to form connections between the cage carrier and the cage, said connections having at least one degree of freedom, the cage comprising two shells (220a, 220b) which are axially assembled to each other, said first or second connection elements comprising broaches oriented radially with respect to said axis X and passing through radial orifices (220a1, 220a2, 220b1, 220b2) of said shells (220a, 220b), characterised in that each of the shells (220a, 220b) comprises tabs (294, 295) evenly distributed about the axis X and being at least partly superimposed in radial direction with the tabs (294, 295) of the other shell (220a, 220b), the tabs (294, 295) comprising one or two orifices (220a1, 220a2, 220b1, 220b2) for mounting each of the broaches. the cage comprising two shells (220a, 220b) which are axially assembled to each other, said first or second connection elements comprising broaches oriented radially with respect to said axis X and passing through radial orifices (220a1, 220a2, 220b1, 220b2) of said shells (220a, 220b), characterised in that each of the shells (220a, 220b) comprises tabs (294, 295) evenly distributed about the axis X and being at least partly superimposed in radial direction with the tabs (294, 295) of the other shell (220a, 220b), the tabs (294, 295) comprising one or two orifices (220a1, 220a2, 220b1, 220b2) for mounting each of the broaches.
