ABSTRACT:
An elongated resilient retainer is positioned between an excavating tooth and tooth holder such that the tooth and tooth holder compress and, thus, deform the retainer to frictionally secure the tooth to the tooth holder. The resilient retainer includes ribs that extend longitudinally along its outer surface. These ribs are circumferentially spaced such that when the retainer is under compression, the ribs engage and grip the upper and lower edges of the tooth adjacent thereto. In this way, the area of surface contact between the resilient retainer and the surface between which it is compressed is augmented to more securely hold the tooth in the tooth holder.
