Abstract
A one-piece nut and sleeve coupling element is provided with an improved frangible connector for effective and reliable shearing of the sleeve member. An interior shear groove is flanked by exterior shear grooves to define a pair of break point webs, one web becoming thinner as the other web is widened upon axial displacement of the interior shear groove from a preselected placement. A shearable break point web is therefore assured when making up a tube fitting utilizing such a one-piece nut and sleeve coupling element.
