• an elongated resilient connecting member having a first end fastened to said first retaining band, and a second end fastened to said second retaining band so that said engagement band portions of said first and second retaining bands are movable away from each other;
• and
• a flexible sleeve disposed around said engagement band portions of said first and second retaining bands and said resilient connecting member such that said resilient connecting member is stretched automatically to an extent corresponding to the size of the foot when the foot is inserted into a space between said sleeve and said foot-supporting portion of said pedal body so as to clamp the foot between said sleeve and said foot-supporting portion of said pedal body, thereby retaining the foot on the pedal body.
