A locking assembly having a substantially joined bracket assembly with a front and back plate defining an opening therebetween with a top slot and a side slot. At least the back plate is directly or indirectly fixedly attached to a solid surface. Positioned within side slot is a pivoting release lever having an upper leg and lower leg movable about a pivot. The pivot is fixedly attached to the front and back plates such that the upper and lower legs are free to move within the opening between the front and back plates within a defined boundary about the pivot. The locking assembly further includes a collar assembly having a collar assembly plate of a size and shape to fit edgewise and be guided into the opening between the front and bottom plates via the top slot. A collar extending from the front surface of the collar assembly plate is attached to a device. The upper leg of the pivoting release lever is positioned adjacent the inserted collar assembly plate and collar in order to pivot and restrain movement of the collar assembly (and device) when the collar assembly plate and collar are inserted into the opening and a front plate opening of the bracket assembly. When a force is applied to the pivoting release lever, the lower leg of the pivoting release lever acts to dislodge the plate and collar (and device) from the openings within the bracket assembly.
