ABSTRACT:
A plurality of retaining pins extending laterally outwardly from the side edges of a sole of a bicyclist's shoe engage in conjugate holes formed in inner and outer spring-loaded retaining plates which extend vertically upwardly from a pedal, thereby securing the shoe to the pedal. The inner retaining plate is laterally movable away from the outer retaining plate by shifting the shoe inwardly, thereby enabling the shoe to be engaged and disengaged from the pedal. The outer retaining plate may be depressed by the shoe and automatically latched into a retracted position inside the pedal body so that the shoe may be secured to the pedal by only the inner retaining plate or may be disengaged completely. The outer retaining plate may be unlatched and released to return to upper position concurrently with movement of the inner retaining plate away from the outer retaining plate.
