ABSTRACT:
A torque transmitting connection between a driving shaft and the core of a reel has a barrel-shaped stub which is rigid and coaxial with the core and extends into a complementary socket of a female coupling element at the respective end of the shaft. The female coupling element has a lateral opening which communicates with the socket, and the stub has a lateral flat so that the thickness of the stub, as measured in a plane including the axis of the stub and extending at right angles to the plane of the flat, is approximately four-fifths of the diameter of the stub. The width of the opening slightly exceeds the width of the flat and the aforesaid thickness of the stub. This renders it possible to insert the stub into or to withdraw the stub from the socket by placing the flat into a plane which is normal to the plane of the opening and by thereupon causing the stub to pass through the opening. When the stub is fully inserted into the socket, it is caused to assume an angular position in which the flat extends across the opening, and the stub is then locked in such angular position by a handle which is pivotally mounted on the female coupling element and has an internal surface which is complementary to and is movable into and from a position of overlap with the flat. The surface bounding the socket of the female coupling element extends along an arc of between 250 and 270 degrees and even in excess of 270 degrees.
