Claim:
A lock assembly for an excavating bucket comprising: (a) a wear member, a base member adapted to receive and mount the wear member, and a lock to releasably hold the wear member to the base member; (b) said wear member being movable longitudinally with respect to the base member into coupling engagement therewith, and said wear member and said base member having respective engaging surfaces to resist transverse movement of said wear member with respect to the base member when said wear member and said base member are in coupling engagement; (c) said wear member and said base member each having a lock-engaging wall, and said wear member defining an opening between said lock-engaging wall of said wear member and said lock-engaging wall of said base member, said lock being receivable through said opening when said wear member and said base member are in said coupling engagement to resist relative longitudinal movement of said wear member to said base member; (d) said lock comprising a lock body and a retainer, said lock body defining a channel extending through the lock body and defining a first opening in a side of said lock body; (e) said retainer being receivable at least partially within said channel, so that a portion of said retainer is selectively extensible from the first opening to an interfering position beyond said side so as to interfere with removal of said lock body from said opening; and (f) said channel defining a second opening in the lock body separate from said first opening, said retainer being accessible by a user via said second opening to be moved internally of said lock body in a direction toward said second opening so as to retract said portion of said retainer from said interfering position when said first member and said second member are in said coupling engagement.
