A pair of identical fastener elements are arranged in superposed, face-to-face relation to cooperatively define a plurality of elongated, peripherally enclosed channels for passage of end portions of strips of material which are thereby joined by the fastening arrangement. Each element has a plurality of arms extending from a connection at one end with a central body portion to a free end, with opposing, spaced edges of the arms and body portions forming slots closed at one end and open at the other. Placing two of the elements in face-to-face, superposed relation with the arms of each element overlying the opposite end of the arms of the other element provides the peripherally enclosed channels. The fastening elements are disclosed in a number of configurations.
