In order to reduce the mass of a primary structure of a mounting pylon for an engine of an aircraft, the mounting pylon includes a box and a rear sub-structure fastened to the box which includes two lateral panels, each equipped at its rear end with a first linking portion through which passes a first connection orifice that is designed to receive a connection pin of a lateral front wing attachment. The rear sub-structure is made in one piece and includes two opposite lateral flanks that are respectively fastened to the two lateral panels of the box by fastening elements. Each lateral flank has a second linking portion through which passes a second connection orifice that is aligned with the first connection orifice, and is also designed to receive the connection pin of the lateral front wing attachment.
