ABSTRACT:
A safety pedal for bicycles includes a spring which includes a retaining arm for locking a metal plate fixed to a shoe sole on the pedal. The spring includes a spiral portion which holds the retaining arm in the locking position. Furthermore, from the spiral portion there extends a single radial arm, arranged on one side with respect to the longitudinal median plane of the pedal, which acts as a torsion bar for allowing swinging movements of the retaining arm when the plate is rotated in the general plane of the pedal to release the plate from the pedal.
