ABSTRACT:
A threaded snap-fit coupling assembly is provided for use in attaching a handle to an implement, such as a paint brush, paint pad, light bulb changer, cleaning brush or the like. The assembly includes an adaptor provided with a cylindrical receptacle and a male fastening member that is externally threaded and sized for threaded receipt in a threaded opening of the implement so that the adaptor may be connected to the implement. The assembly also includes a coupling provided with a first end that is retained on the handle, and a cylindrical male portion that is externally threaded and sized for threaded receipt in the opening of the implement and for sliding receipt within the receptacle of the adaptor. The coupling is retained on the adaptor via a snap-fit connection when the male portion of the coupling is received in the receptacle of the adaptor. This connection permits removal of the coupling from the adaptor when the coupling is pulled from the receptacle with a force sufficient to overcome the holding force of the snap-fit connection.
