Abstract
A spring clip is capable of selective installation on and removal from a pair of adjacent pins in a roller chain. The spring clip has a body portion formed of sheet spring metal and an opening at each of its opposite ends. The intermediate section of the body portion is preformed into an arc to establish a predetermined linear distance between the openings. The openings may only be simultaneously received by and installed at recesses at the extended ends of each pin by deforming the arc of the intermediate section to alter the distance between the openings to a magnitude generally corresponding to a predetermined distance between the pins. When both openings are simultaneously installed at the recessed portions of their respective pins, the arc of the intermediate section tends to re-establish the predetermined linear distance to prevent inadvertent removal of the spring clip from the pins.
