Abstract: A locking means secures together opposite ends of a baling wire for securing bales of compressed material. Predetermined lengths of baling wire are dispensed and wrapped around a bale and secured by a locking means comprising a metal clip having a raised arcuate center portion spaced outwardly from the peripheral supporting member but connected thereto at either end of the raised arcuate portion. Each arcuate connection forms a crotch between the peripheral support member and the raised arcuate member wherein each end of the baling wire passes transversely therethrough and securely locks therein.
