A cable tie for releasably bundling together a plurality of elongated objects. The cable tie includes an elongated band for circumscribing the plurality of elongated objects, and a locking head disposed thereon. The locking head includes a chamber and a chamber entry and exit, and an appropriately dimensioned ball disposed within the chamber such that the ball may assume one of at least two positions within the chamber, a first, generally free position when the band is being forwardly urged through the chamber and a second, generally restricted position when the band is being backwardly urged through the chamber, wherein when the band is being forwardly urged through the chamber the ball does not frictionally restrict the band in response to the forward urging, thereby permitting forward movement of the band through the chamber, and when the band is being backwardly urged through the chamber the ball frictionally restricts the band from substantial backward movement through the chamber in response to the backward urging. There is also an opening in the locking head for providing access to the ball by an implement such that the implement may be used to urge the ball from the second position toward the first position whereby the band may be urged backwardly and thereby moved backwardly through the chamber without the ball frictionally restricting the backward movement of the band as it would in the absence of the implement.
