Abstract

A strong, easy to use tab and slot fastening device suitable for use with disposable absorbent articles. The fastening device preferably includes a tab member and a slot member. The slot member has an inboard portion, an outboard portion and a slot. The inboard portion located laterally inboard of the outboard portion and the slot located between the inboard portion and the outboard portion. The tab member has a length, a proximal edge, a distal edge and a lip portion. The tab portion is passed through the slot of the slot member to engage the fastening device. Once passed through the slot, at least the lip portion of the tab member pivots such that it overlaps the outboard portion of the slot member to prevent the tab member from disengaging from the slot member.
