Claim:
1. An injection manifold assembly for a turbomachine, the injection manifold assembly comprising: a first set of transfer tubes connected so as to form a main circuit for feeding fuel to at least a first set of injectors and a second set of injectors; a second set of transfer tubes connected in parallel with the first set of transfer tubes so as to form an auxiliary circuit for feeding fuel to said first set of injectors; and a double coupling presenting at least one first endpiece receiving one end of a transfer tube of the main circuit, a second endpiece receiving one end of a transfer tube of the auxiliary circuit, and a mounting surface with a first orifice in fluid flow communication with the first endpiece and a second orifice in fluid flow communication with the second endpiece, said mounting surface of the double coupling being suitable for connecting the double coupling to an injector of said first set of injectors; and a single coupling presenting at least a first endpiece receiving one end of a transfer tube of the main circuit, and a mounting surface with an orifice in fluid flow communication with the first endpiece, said mounting surface of the single coupling being suitable for connecting the single coupling to an injector of said second set of injectors.
