The invention claimed is: 1. A wheeled platform for coupling to a pushchair, in particular for transporting a standing child, the platform comprising a footplate provided with wheels and at least one coupling arm having a first end fitted to the footplate and a second end adapted to co-operate with means for securing it to the pushchair, wherein the first end of the coupling arm is received directly in an orifice of the footplate, without any intermediate part, wherein the orifice and the first end of the arm are smooth, wherein the platform includes axial and angular stop means for holding the arm relative to the footplate, and wherein the stop means comprises a screw for tightening against the first end of the coupling arm. 2. The platform according to claim 1, wherein the orifice extends in a direction that is substantially perpendicular to the footplate. 3. The platform according to claim 1, wherein the orifice extends in a direction that is substantially perpendicular to the footplate, and wherein the screw extends from a side of the footplate. 4. The platform according to claim 1, wherein the second end is connected to a fastener sleeve suitable for being detachably fitted to a coupling member fitted to the pushchair. 5. The platform according to claim 4, wherein the connection between the second end and the fastener sleeve is slidable in order to adjust the length of the coupling arm, with locking being provided in a plurality of predetermined axial positions. 6. The platform according to claim 4, wherein the fastener sleeve includes fastener members for fastening to the coupling member, said fastener members providing angular indexing of the fastener sleeve relative to the coupling member. 7. The platform according to claim 6, wherein the fastener sleeve is fitted on a ferrule pivotally mounted on the coupling member, the coupling member including indexing members for indexing the ferrule relative to the coupling member. 8. A wheeled platform for coupling to a pushchair, in particular for transporting a standing child, the platform comprising a footplate provided with wheels and at least one coupling arm having a first end fitted to the footplate and a second end adapted to co-operate with means for securing it to the pushchair, wherein the first end of the coupling arm is received directly in an orifice of the footplate, without any intermediate part, wherein the orifice extends in a direction that is substantially parallel to the footplate and perpendicularly to a vertical midplane of said footplate, wherein the orifice is smooth and the first end of the coupling arm comprises a cylindrical shaft segment presenting axial fluting, and wherein the platform includes axial and angular stop means for holding the arm relative to the footplate and co-operating with said axial fluting. 9. The platform according to claim 8, wherein the stop means comprise a shoe movable between an active, locking position and an inactive, unlocking position, said shoe presenting a fluted bearing surface that co-operates in the active position of the shoe with the axial fluting of the cylindrical shaft segment in order to provide axial and angular locking. 10. The platform according to claim 8, wherein the second end is connected to a fastener sleeve suitable for being detachably fitted to a coupling member fitted to the pushchair. 11. The platform according to claim 10, wherein the connection between the second end and the fastener sleeve is slidable in order to adjust the length of the coupling arm, with locking being provided in a plurality of predetermined axial positions. 12. The platform according to claim 10, wherein the fastener sleeve includes fastener members for fastening to the coupling member, said fastener members providing angular indexing of the fastener sleeve relative to the coupling member. 13. The platform according to claim 12, wherein the fastener sleeve is fitted on a ferrule pivotally mounted on the coupling member, the coupling member including indexing members for indexing the ferrule relative to the coupling member.
