Abstract
Telescoped ground engaging telescoped wear and support members are provided with self-adjusting connector apparatus that releasably retains the wear member in a rearwardly telescoped orientation on the support member. In illustrated embodiments thereof, the connector apparatus includes cooperating ratchet structures operatively associated with the support and wear members and functioning to automatically re-tighten an abrasion-created loosened interfit between the wear and support members in response to a rearwardly directed operational force imposed on the wear member.
