A break-away coupling is formed of metal and has a central axis and a necked-down central region formed by two inverted truncated cones each having larger and smaller bases. The cones are joined at the smaller bases by a narrowed transition region having an exterior surface formed by a curved surface of revolution having an inflection point of minimum diameter substantially midway of the coupling along the axis. The cones each define an angle &#x3b8;and &#x3b8;, respectively, at each of the larger bases, wherein both &#x3b8;and &#x3b8;are selected to be within the range of 20&#xb0;-40&#xb0; and, preferably within the range of 30&#xb0;-37&#xb0;.
