ABSTRACT:
In a zip fastener the elements (10) on one tape have a head which engages a shoulder (20) of an opposed element to limit out of plane movement. A small number of elements (30) have a head (38) which bears on a shoulder46when twisted in one direction but passes the shoulder (46) when twisted in the opposite direction to allow partial separation of the elements to create a point of weakness. The coupled elements can be peeled apart when sufficient pressure is applied to one side of the tape at the point of weakness, but the elements resist twisting when pressure is applied to the opposite side.
