A coupling mechanism for quick attach/disconnect of a control fin to a missile which does not require the use of a separate tool to make the attachment. A first coupling member (24) is mounted on the control fin actuator rod (16). A force regulating means comprised of a spring (28) and retainer bracket (58) are attached to the first coupling member. A second coupling member (26) and a pivotable lever arm (38) are formed as part of the control fin. When the second coupling member is loosly fitted upon the first coupling member, rotation of the lever arm will engage the force regulating means thereby deflecting the spring (28). The reactive force of the spring is exerted through the lever arm, through the control fin, and causes the second coupling member to firmly and securely engage the first coupling member. A means is provided to lock the lever arm in place so as to retain the first and second coupling members in the firmly engaged position even through extreme aerodynamic maneuvers. The lock is easily disengaged manually should it be necessary to remove a control fin from the missile.
