Abstract
The pedal includes a pedal body (1) rotationally mounted on a pedal shaft. The pedal body (1) includes a fixed front catch element (4) and a movable rear catch element (6) that work with a retaining plate (3) fixed underneath the footwear of the cyclist. The movable rear catch element (6) is mounted to be able to pivot between a retaining position of the plate (3) and a position of release of the plate (3) by the pivoting of the rear catch element (6) in opposition to the action of an elastic return element (10). The elastic return element (10) is composed of an elastic leaf that forms a spring located in a longitudinal housing (11) of the pedal body (10) open to the rear, the leaf (10) being able to be stressed along its longitudinal axis in buckling during pivoting of the rear catch element.
