Coupling assembly

A threaded snap-fit coupling assembly for use in attaching a handle to an implement provided with a threaded opening of a predetermined diameter, the assembly comprising:

• an adaptor including a cylindrical receptacle having a diameter larger than the predetermined diameter of the threaded opening, and a male fastening member that is externally threaded and sized for threaded receipt in the opening of the implement so that the adaptor may be connected to the implement;
• a coupling including a handle engaging means for retaining the coupling 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;
• and
• a snap-fit connection means exerting a holding force on the coupling when the male portion of the coupling is received in the receptacle of the adaptor for retaining the coupling on the adaptor, the connection means permitting 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 means.
