Abstract An improved fastening device for securing the corners of disposable diapers which includes a strip of pressure-sensitive tape held in superposed relationship with respect to a corner of the plastic backing sheet prior to use. One end of the tape is directly adhered to the plastic backing sheet. A treated release liner is interposed between the other end of the tape and the plastic backing sheet. The release liner is directly adhered to the backing sheet whereas the tape is releasably held in contact with the release liner. Securement means are provided for holding down the releasable end of the tape and maintaining it in contact with the release liner for the purpose of preventing inadvertent removal. The tape has a tab end between the securement means and the extremity of the releasable end of the tape to facilitate easy removal from the release liner when preparing the tape for fastening and holding the adjoining corners of a diaper.
