A camming coupler for removably attaching a music desk or other object to an upright support leg. The camming coupler includes an inner sleeve for receiving the upright support leg. The inner sleeve has at least one longitudinal slit formed therein, and preferably has four substantially equidistant longitudinal slits. The inner sleeve also has a cammed exterior surface. An attachment member extends from the inner sleeve, and is attachable to the music desk or other object. The camming coupler further includes an outer sleeve positioned over the inner sleeve. The outer sleeve has a cammed interior surface that corresponds with the cammed exterior surface of the inner sleeve. In use, the camming coupler is secured to a music desk or other object. An upright support leg is inserted in the inner sleeve, and the outer sleeve is rotated to compress the inner sleeve.
