Abstract
A barbed tape is disclosed incorporating an improved barb configuration. A flat metal tape is formed having opposed barbed pairs that extend from a central portion at an angle to thus point the tips of the respective barbs away from the longitudinal axis of the tape. The central strip of the tape is clenched about a central core wire; intermediate barbs are provided to increase the effectiveness of the barrier while providing a means for positively positioning clips that are used to secure adjacent coils of the tape together.
