The first adhesive tape has a free end portion which is adapted for attachment to a marginal portion of the front surface of the diaper and a fixed end which is joined to the adhesive face of a second adhesive tape. The second adhesive tape has a free end portion which is adapted to form a first fastening tab and a fixed end which is joined to the adhesive face of a third adhesive tape. The third adhesive tape has a first free portion which is adapted to form a second fastening tab and a second free end portion which is adapted for attachment to a marginal portion of the back surface of the diaper to form a second anchor tab. The second anchor tab is finger tearable whereby in use it can be detached from the fastener to allow the first fastening tab to be used to refasten the diaper.
