System for connecting and locking blades which are fixed circumferentially to a rotor disc (1) of an axial compressor, comprising a plurality of blades (10, 10') positioned in an array along the circumference of a rotor disc (1), each blade (10, 10') being provided with a shaped root (13) for connection to the rotor disc (1), and means of positioning and locking the blades (10, 10') which can lock them in a predetermined position in a circumferential seat (3) which has a shaped profile and which is formed along the circumference of the rotor disc (1). At least one insertion slot (4) intersects the said circumferential seat (3) to permit the insertion of the roots (13) of the blades (10, 10') and the positioning and locking means.
