<p>The quick-action coupling has two complementary halves allowing free rotation but secured in the axial direction. The halves (16) have integral securing portions (23), no additional devices being required to hold them together. They can have edges running in the lengthwise direction, and oblique holding surfaces (23) engaging together, being fitted together in the radial direction so that the edges bear against each other in the plane of the lengthwise axis. Each half can also have a boss and a protrusion at one edge, and a hole and slot at the other.</p> |
