A clip assembly may safely secure sliding sashes of a window or door during transportation, and, in one embodiment, be comprised of a strap member and a pawl member. The strap member may be comprised of a bumper portion, and a strap portion extending therefrom, where the strap portion may have a plurality of teeth formed within the thickness of the strap. The pawl member may have a pair of sidewalls supported by a top wall and an intermediate wall. The top wall may have a protrusion which includes a plurality of pawl teeth formed to complement the strap teeth, and be located proximate to the intermediate wall. The strap may be introduced through the gap between the top rail of an upper sash and bottom rail of the second sash, to then be inserted into the pawl, and thereby be retained by the respective teeth to secure the sashes.
