A quick coupling device for use in cold environments such as the Arctic to joint two shafts in an end-to-end relation which comprises a first hollow cylindrical body on one shaft end which has a cut out portion and carries a hollow, internally threaded stud opposite the cut out portion, and a second hollow cylindrical body carried by the other shaft end which has a corresponding cut out portion so that the first and second bodies can be mated together to form a continuous cylindrical body from one shaft end to the other shaft end, the second cylindrical body having a plate across the cut out portion with an aperture therein which aperture registers with the open end of the stud means when the first and second cylindrical bodies are mated whereby a threaded pin means can then be screwed into the stud means from outside the first cylindrical body and said pin means will extend through said stud means and into the plate aperture to physically join the first and second cylindrical bodies and, therefore, the two shafts ends to one another.
