Abstract
Abstract A one-piece bundle tie comprising a strap having at one end a lock member into which the other end of the strap can be inserted. One face of the strap is provided with a plurality of transverse teeth, each tooth having locking faces formed as a chevron. The lock member comprises a head having an aperture therethrough to pass the strap and a pawl carried therein, the distal faces of the pawl having a chevron configuration in correspondence to and for cooperative engagement with the chevron-formed tooth faces of the strap. The pawl is dependent from a ledge within the locking head aperture, the ledge having lateral faces extending between opposite walls of the aperture and spaced from said opposite walls to impart flexure to the pawl.
