A collapsible golf club. A head is disposed on a shaft and a coupling replaceably couples an end of the handle to an end of the shaft. The coupling includes a threaded portion extending from the end of the shaft, a stub shaft extending from the threaded portion, a pair of pins extending radially outwardly from the stub shaft, a tube extending from the end of the handle and having a pair of slots and a shoulder, and a sleeve having an internal threaded portion and terminating in a lip. The tube is rotatably captured in the sleeve, up against the internal threaded portion, and is maintained therein by the lip providing a stop for the shoulder, thereby rotatably attaching the sleeve to the tube. The stub shaft passes through the internal threaded portion and into the tube, with the pair of pins entering the pair of slots, with the internal threaded portion threadably engaging the threaded portion, and with the sleeve being rotated until the pair of pins snug into the pair of slots, thereby providing a tight joint between the shaft and the handle.

The invention claimed is: 1. A collapsible golf club, comprising: a) a shaft; b) a handle; c) a head; and d) a coupling; wherein said head is disposed on said shaft; wherein said coupling replaceably couples an end of said handle to an end of said shaft; wherein said coupling comprises a threaded portion; wherein said coupling comprises a stub shaft; wherein said coupling comprises a pair of pins; wherein said pair of pins of said coupling extend radially outwardly from said stub shaft of said coupling; wherein said pair of pins of said coupling are diametrically opposed to each other; wherein said coupling comprises a tube; wherein said tube of said coupling has a terminal portion; wherein said terminal portion of said tube of said coupling is larger in diameter than a remaining portion of said tube of said coupling so as to provide a shoulder around said tube of said coupling; wherein said terminal portion of said tube of said coupling has a pair of slots; wherein said pair of slots in said terminal portion of said tube of said coupling are diametrically opposed to each other; wherein each slot is defined by a pair of walls; wherein said pair of walls defining each slot both converge axially in said terminal portion of said tube of said coupling; wherein said coupling comprises a sleeve; wherein said sleeve of said coupling has an inner portion; wherein said sleeve of said coupling has an outer portion; wherein said sleeve of said coupling has an internal threaded portion; wherein said internal threaded portion of said sleeve of said coupling divides said sleeve of said coupling into a threadless said inner portion of said sleeve of said coupling and into a threadless said outer portion of said sleeve of said coupling; and wherein said stub shaft of said coupling passes through said outer portion of said sleeve of said coupling, through said internal threaded portion in said sleeve of said coupling, and into said tube of said coupling, with said pair of pins of said coupling entering said pair of slots in said terminal portion of said tube of said coupling, with said internal threaded portion in said sleeve of said coupling threadably engaging said threaded portion of said coupling, and with said sleeve of said coupling being rotated until said pair of pins of said coupling snug into said pair of slots in said terminal portion of said tube of said coupling, thereby providing a tight joint between said shaft and said handle. 2. The club of claim 1, wherein said threaded portion of said coupling extends from said end of said shaft. 3. The club of claim 2, wherein said threaded portion of said coupling extends collinearly from said end of said shaft. 4. The club of claim 2, wherein said threaded portion of said coupling is smaller in diameter than said end of said shaft. 5. The club of claim 1, wherein said stub shaft of said coupling extends from said threaded portion of said coupling. 6. The club of claim 1, wherein said stub shaft of said coupling extends collinearly from said threaded portion of said coupling. 7. The club of claim 1, wherein said stub shaft of said coupling is smaller in diameter than said threaded portion of said coupling. 8. The club of claim 1, wherein said tube of said coupling extends from said end of said handle. 9. The club of claim 1, wherein said tube of said coupling extends collinearly from said end of said handle. 10. The club of claim 1, wherein said tube of said coupling is smaller in diameter than said end of said handle. 11. The club of claim 1, wherein said inner portion of said sleeve of said coupling terminates in a lip. 12. The club of claim 11, wherein said lip of said inner portion of said sleeve of said coupling extends inwardly therearound so as to provide a reduced opening thereat. 13. The club of claim 12, wherein said remaining portion of said tube of said coupling passes into said reduced opening of said inner portion of said sleeve of said coupling, and said terminal portion of said tube of said coupling is rotatably captured in said inner portion of said sleeve of said coupling, up against said internal threaded portion in said sleeve of said coupling, and is maintained therein by said lip of said inner portion of said sleeve of said coupling providing a stop for said shoulder of said terminal portion of said tube of said coupling, thereby rotatably attaching said sleeve of said coupling to said tube of said coupling.
