The pedal further includes an adjustment system (8) for adjusting a return force of the elastic return means in order to adjust a shoe attachment/detachment tension. In accordance with the invention, the elastic return means includes a variable number of elastic members (70-72) each having one end connected to the rear attachment member (4) and another end connected to the pedal body (1), selected from a plurality of elastic members (70-72) extending between the rear attachment member (4) and the pedal body (1). The adjustment system (8) is adapted to select the elastic members constituting said elastic return means in order to achieve a predefined shoe attachment/detachment tension value.
