<p>A coupling (200) includes a first element (210) having an annular projection (210) and a second element (240) having an annular recess (250). Both the first element (210) and the second element (240) have a common axis (205). A radius of the annular projection (210) varies circumferentially around the axis (205) to thereby define a connection profile (270). The annular projection (210) is removably accommodated within the annular recess (250) to couple the first (210) and second (240) elements to one another.</p> |
