Tooth assemblies having a tip with ears extending rearwardly therefrom to mate with corresponding slots in an adapter are normally utilized in order to aid in the transfer of forces from the tip to the adapter. In the subject arrangement, a tip (12) includes a pair of opposed ears (32, 34) each having a pair of opposed edge surfaces (40, 42) that are angled one relative to the other. The pair of opposed ears (32, 34) of the tip (12) mates with a pair of corresponding opposed slots (54, 56) defined by the adapter (14). The pair of opposed slots (54, 56) in the adapter (14) likewise has a pair of opposed edge surfaces (60, 62) angled with respect to one another and are in confronting mating relationships with the pair of opposed edge surfaces (40, 42) of the pair of opposed ears (32, 34). This inhibits any outward movement of the pair of opposed ears (32, 34) with respect to the adapter (14).
