[0037] The fastener 100 or 200 includes a first, hook tape 101/201, and a second, loop tape 102/202, that are reversibly interconnectable. When used with a brasserie, the hook tape 101/201 is attached, for example by way of a seam, to one arm of the brasserie and the loop tape 102/202 is attached, for example by way of a seam, to another arm of the brasserie. Another possible way of attaching the hook and loop tapes 101/102/201/202 to respective arms of the brasserie may involve adhesive or ultrasonic welding. When fastened, hook and loop connectors 101A/201A/102A/202A on the hook and loop tapes 101/102/201/202 connect the arms of the brasserie to form a complete loop.
[0038] The hook tape 101/201 of both of the first and second embodiments includes a plurality of hook connectors 101A/201A extending from a backing sheet 101B/201B, which collectively forms a layer of hook connectors. The backing sheet 101B/201B are supported on a base layer 101C/201C. More specifically the layer of hook connectors is attached, directly or indirectly and possibly by way of adhesive, to the base layer 101C/201C for support. An attachment portion 101D/201D is provided at one end of the hook tape 101/201 and adjacent the hook connectors 101A/201A. A gripping portion 101E/201E is provided at another end of the hook tape 101/201 and located opposite to the attachment portion 101D/201D. The gripping proton 101E/201E and the attachment portion 101D/201D are devoid of any hook connectors 101A/201A. A window is defined between the gripping portion 101E/201E and the attachment portion 101D/201D through which the hook connectors 101A/201A are exposed. The attachment portion 101D/201D includes a retainer 101D1/201D1 which is an opened end dimensioned to receive the arm of a brasserie.
