1. A turbomachine part of an annular assembly extending around an axis, the part comprising a structural body and at least one connecting edge, each connecting edge having at least one groove receiving a sealing tab, wherein each connecting edge is made of composite material comprising a fibrous reinforcement consisting of randomly-oriented short fibres, said reinforcement being densified by a ceramic matrix, wherein the structural body is made of a material different from the composite material comprising a fibrous reinforcement consisting of randomly-oriented short fibres of said at least one connecting edge and wherein said at least one connecting edge is fixed on the structural body, wherein the part is a turbine ring sector extending in an annual manner around an axis, the sector comprising a sector structural body having an annular base having an inner face adapted to define the inner face of a turbine ring when the ring sector is mounted on a ring support structure, and an outer face from which one or more attachment portions of the ring sector extend to the ring support structure, the ring sector further comprising two inter-sector connecting edges at the circumferential ends of the sector structural body, each inter-sector connecting edge being adapted to be opposite a circumferentially neighbouring ring sector when the ring sector is mounted on the ring support structure, each inter-sector connecting edge having one or more grooves each adapted to receive the sealing tab.
