Abstract: A two-piece adjustable waistband assembly includes a track member and a latch member. The track member is sewable to the underlying part of a waistband, and the latch member is sewable to the overlying part of the waistband and is adapted for receiving the track member. The latch member is formed with a pawl which is resiliently biased into rectangularly-shaped slots formed within the track member, thereby detachably interengaging the latch member with the track member. The latch member may be lifted at its one end so as to cause disengagement of the pawl from the recesses so as to permit movement of the latch member along the length of the track member.
