Abstract: A quick release locking mechanism suitable for use as a cymbal retainer includes an adaptor threadably enageable on a cymbal support rod. A collar member adjustably positionable along the adaptor has a tapered socket aperture for accommodating a spherical keeper element. A locking ring surrounding the collar includes a circumferential camming surface rotationally displaceable for selectively urging the spherical element into engagement with the adaptor to secure the collar. An eccentric channel portion provides a pocket for receiving the spherical element to release the collar.
