A plurality of belt fasteners are joined together by intermediate bridging portions which may break off and leave the adjacent belt fastener edges spaced from each other by the width of the bridging portions when the belt is in use. The preferred fasteners are plate fasteners joined together in a strip of these frangible bridge portions. Preferably, a pair of lines of weakness are formed by stamping parallel notches adjacent either edge of the plate fastener so that substantially all of the bridging material between adjacent fasteners may break off thereby leaving a sizeable gap between adjacent sides of adjacent fasteners. |
