A clip for removably attaching a cubicle wall extension element to a top surface of a cubicle wall includes two elongate arms rotatably coupled together at an attachment portion. Each one of the arms has an upper portion and a lower portion, and the attachment portion is disposed between the upper portion and the lower portion. Each one of the arms also has a first angled portion between the lower portion and the attachment portion, and a second angled portion between the attachment portion and the upper portion. A space between the lower portions of the arms is sized and shaped to fit over the top surface of the cubicle wall. A torsion spring is disposed between the two arms so that the two arms are spring biased to have a resting configuration in which the lower portions of the arms are open and the upper portions of the arms are closed.
