ABSTRACT:
A fastener has two interengageable halves. Each half has first and second elements extending along the length dimension of the fastener. The two elements are interconnected, in a direction transverse to the length of the fastener, by a resilient part which is tensioned in the separated state of the fastener and relaxed in the joined state. In the zone of the separated state the tensioned state of the resilient part is maintained by a stable engagement of the first and second elements of each fastener half. In the zone of the joined state the first elements of the two halves are in an interengaging stable relationship. During release of the first first element with respect to the second element of each fastener half in the presence of the first element of the one fastener half between the two elements of the other fastener half, the resilient parts urge the first elements into the respective other fastener half and effect self-propagation of the boundary between the zones of the separated state and the joined state.
