A quick release coupling for connecting a driven shaft having a universal type joint at one end thereof, with a drive shaft, includes a coupling box surrounding the drive shaft and a coupling sleeve carried at the end of the driven shaft for axially receiving an end of the drive shaft. An annular groove is located on the drive shaft and a ball-catch mechanism is carried by the coupling sleeve for snap acting cooperative engagement with the annular groove to produce a positive form fitting engagement between the drive shaft and the coupling sleeve. A locking ring is carried for movement on the coupling sleeve between a release position and a locking position for locking the ball-catch mechanism into engagement with the groove. A spring is used to bias the locking ring into the locking position. Means are provided for engaging the locking ring to hold it in the release position during insertion and removal of the drive shaft into and out of the coupling sleeve. A release lever is pivotally mounted on the coupling box for engaging the locking ring to move it into a release position allowing the ball-catch mechanism to be released from the annular groove so that the shafts may be easily disconnected.
