Zusammenfassung:	A coupling arrangement for securing two separable components in an excavating operation includes a wear component, a base component and a lock. The lock has a body having a configuration adapted to be received in a hole in the base component, and a rotatable locking member. The locking member includes a flange that is movable between a locking position wherein the flange holds the lock in the assembly and a release position wherein the flange permits the lock to be removed from the assembly. In the release position, the flange sets within the axial extension of the outline of the body. In the locking position, at least part of the flange sets outside the axial extension of the outline of the body. In one construction, the rotation of the locking member to the locking position tightens the fit of the wear component on the base component.
