1. A planet carrier for a speed reduction gear of a turbomachine, the planet carrier having a main axis X and comprising:
a cage carrier comprising an annular row of axial fingers about the axis X, which carry first connecting 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 disposed about the axis X and meshed with said sun gear and with a ring gear for surrounding the cage, housings at a periphery of said cage,
second connecting elements mounted in said housings and cooperating with the first connecting elements to form connections between the cage carrier and the cage, which allow at least one degree of freedom between the cage carrier and the cage, and
two shells which are axially fixed to each other and separated from each other by a plane, said housings being formed respectively in said shells, each of said housings comprising a first orifice formed in a first of the shells and a second orifice formed in a second of the shells, the first and second orifices being aligned,
wherein the shells comprise at their external periphery radial tabs extending perpendicularly to the main axis X and to axes tangent to a circumference centered on said main axis X, said radial tabs being in axial support against each other or axially spaced from each other and in which said first and second orifices are formed respectively, and
wherein the radial tabs have a dimension along the main axis which is lower than a dimension of each shell along the main axis.
