ABSTRACT:
A clip is disclosed for connecting two adjacent loops of segment bent helical barbed tape in close proximity to one another at a nesting point of two contiguous folds to form a concertina antipersonnel barrier. The clip includes first and second opposed flaps. The first flap includes an elongated semi-circular aperture extended therethrough and dimensioned to surround the contiguous folds in their entirety such that the clip reinforces the areas of stress concentration that lie proximate the contiguous folds. The second flap includes an identical elongated semi-circular aperture extended therethrough which functions to promote stacking of adjacent coils of helical barbed tape during storage. The clip further includes a unitarily formed locking mechanism defined by an extruded cylindrical sleeve disposed on the first opposed flap and a circular aperture extended through the second opposed flap. In operation the extruded cylindrical sleeve is extended through the circular aperture and compressed so as to expand outwardly and form an eyelet connection, thereby securing two adjacent loops of helical barbed tape.
