CA 2386971

The fastener includes a pin and a body. The pin includes longitudinal grooves which communicate with partially threaded grooves which traverse the circumference of the shank by an integer multiple of 180°. Retention fingers engage the longitudinal grooves in the pre-installed configuration and allow straight-line insertion of the pin into the body. The retention fingers are then urged outwardly by the walls of the partially threaded grooves and then snap engage into subsequent portions of the partially threaded grooves thereby preventing straight-line removal of the pin. The pin, however, can be subsequently removed by threaded rotating the pin until the retention fingers engage the longitudinal grooves. Thereafter, the pin can be manually removed by a straight-line motion.
