ABSTRACT:
An improvement is provided in apparatus for securing overlapped portions of two members together. In addition to a wedge conventionally inserted in holes generally axially aligned in the overlapped portions, a locking bar is provided for insertion longitudinally in the holes and has a notch with opposed faces for tightly engaging the outer surfaces of one of the members which is subject to less flexing movement than the other. The wedge and bar are secured together after insertion to prevent loosening of the wedge in service.
