ABSTRACT:
A quick-attachment fastener has an elongate barrel and a plunger translatable in forward and aft directions in the barrel. A pivot pin in the barrel extends through the plunger and has an axis fixed relative to the barrel. An arm on the pin swings between a retracted position in the barrel and a deployed position where the arm extends from the barrel. An aft facing part of the plunger engages the arm so that a spring biasing the plunger urges the arm toward the deployed position. A forward facing part of the plunger opposes the arm so that aft plunger translation swings the arm to the retracted position.
