Abstract: The invention relates to a novel locking assembly including a readily removable handle arrangement that can be quickly and easily interchanged with any number of other handles having whatever configuration is desired. This is accomplished by introducing an adaptor between the conventional locking mechanism and the handle that facilitates the rapid interchange. Specifically, the adaptor includes the key core and defines an outer end surface having a raised portion of an elliptical shape and a corresponding handle that has an end opening that conforms to the elliptical shape and when in place is secured to the adaptor.
