The window bead assembly 100 has a bead 300 and a clip 200 for receiving the bead, in which the bead and clip are couplable by pressing the bead into the clip in an insertion direction, and wherein the bead and clip are uncouplable by urging the bead in a direction not aligned with the insertion direction. The bead and clip may be disconnected by forcing the bead in one direction not aligned with the insertion direction, but may resist disengagement when the bead is urged in another direction not aligned with the insertion direction. Detachment may be impeded when the bead is rotated in one direction, and permitted when the bead is rotated in an opposite direction.
