The clip comprises a front plate having opposing end sections; offset members extending backwardly from the opposing end sections; and, opposing securing members extending downwardly from the back of the offset members. Adjacent sound absorbing panels are placed together by the securing members of the clip being placed between sound absorbing material and the frame of two adjacent panels. The sound absorbing panels may be either individual, smaller panels or may be a larger panel made up of smaller panels, stacked one on top of the other, and having a vertical frame member common to the vertical edges with the frame member having a U-shaped cross-section.
