Abstract: A universal mounting assembly for quick mounting of an object to a stand device. The mounting assembly includes a body having a support surface, a front face and an opposed mounting surface configured to mount to the support stand. The front face intersects the support surface and defines an opening into a receiving socket of the body. An elongated slot extends along and into the receiving socket from the support surface, and includes a transverse width dimension smaller than that of the receiving socket. The receiving socket receives the transverse width dimension of the head portion therein as the neck portion simultaneously slides along the elongated slot to a dock position. A resilient retaining arm includes a contact portion movable between a released position and a locked position. A manually operable locking wedge prevents movement of the retaining arm from the locked position toward the released position.
