Abstract: A device comprising a shaft and a fastener. The device requires substantially no tools to apply while generally maintaining the basic shape of a common clevis pin and the robustness of a common cotter pin. The fastener passes through a bore hole in the shaft. A cap positions onto a shaft head, and includes a ridge that engages a slot in the shaft head. The cap and head have low profiles and are non-protuberant, so as to minimize snagging, inadvertent release, and/or damage to contacting objects. A plunger positions inside the shaft, passing through a plunger spring. The plunger spring provides a compressive force that presses against the fastener to hold it in place. Removing the cap reduces the compressive force. The shaft cannot be released by external pressure on the shaft head. A compressive element helps secure the fastener in a shaft cross bore.
