Abstract
A system for coupling synthetic boomsticks having a pair of spaced parallel substantially horizontal coupling flanges projecting axially therefrom. The flanges form a loop receiving space therebetween and a coupling pin passes through this space between the flanges to lock a loop therein. The coupling pin is lockable in closed position to hold loop in place. A coupling pin and slot prevents rotation of the coupling pin except when the coupling pin is in retracted open position.
