RF connector

A connector for an elongated cylindrical element having a deformable jacket surrounding a core includes an inner member having a sleeve, characterized by a diameter and thickness adapted to allow the sleeve to be inserted between the jacket and the core and to extend longitudinally into a space between the jacket and the core a first distance, an outer sleeve spaced radially outside the inner sleeve to form a cavity therebetween for receiving a portion of the deformable jacket, the outer sleeve extending longitudinally along the cylindrical element a distance less than the first distance; and an outer member rotatably disposed on the cylindrical element and slidably movable with respect to the inner member, and having a first cavity for receiving the inner member and a radially inwardly extending flange for engaging the deformable jacket and deforming at least a portion of the jacket radially outwardly to anchor the connector with respect to the elongated cylindrical element.
