Claim:
1. A turbine engine vane, the vane being made of composite material comprising a fiber reinforcing structure densified by a matrix and comprising: a hollow airfoil having an internal passage extending along its entire length between a pressure side wall and a suction side wall of the airfoil, an inner platform, and an outer platform, wherein the airfoil is extended on the outside of the outer platform by an upstream attachment portion and by a downstream attachment portion for mounting the vane in a casing, the upstream attachment portion includes an upstream attachment tab that is an extension from the pressure side wall or the suction side wall of the airfoil, the upstream attachment tab being rounded in shape to extend at an angle to the pressure side wall or the suction side wall from which it extends, the downstream attachment portion includes a downstream attachment tab that is an extension from the pressure side wall or the suction side wall of the airfoil, the downstream attachment tab being rounded in shape to extend at an angle to the pressure side wall or the suction side wall from which it extends, and the fiber reinforcing texture of each of the upstream attachment tab and the downstream attachment tab is in continuity with the fiber reinforcing texture of the pressure side wall or the suction side wall in line with which the tab is situated.
