Abstract
Various implementations include a slide fastener that has a blocking element on one stringer that prevents engagement compatibility with standard elements on the other stringer. For example, at least one blocking element is coupled to a first stringer, and first and second blocking coupling elements are coupled to a second stringer. The contour of the blocking element and the contour of the blocking coupling elements are different from the contour of the standard elements on the stringers such that the standard elements do not engage with the blocking element or the blocking coupling elements in an alternating arrangement. However, the contour of the blocking element and contour of the blocking coupling elements allow for the engagement of the blocking element with the blocking coupling elements in an alternating arrangement.
