A clasp is configured to permanently interlock around a flexible strip of material and includes first and second interlocking members. Each interlocking member includes two hooks and two recesses. Each of the hooks of the first side are arranged to engage and interlock with one of the recesses of the second side and each of the hooks of the second side are arranged to interlock with one of the recesses of the first side, so as to prevent movement between the interlocking members when interlocked.
