<p>The coupling (1) is intended for securing a handle (5) to a tool (8) e.g. a broom or rake. It comprises a hollow element (2) secured to or part of the tool and provided with an internal taper screw thread (4), to grip the end of the handle. A clamp is provided for the end of the handle, e.g. circumferentially spaced axially projecting resilient lips (10). These clamps are radially inwardly pressed by a screw bush (3) around the end of the handle, with an internal screw thread (13) fitting on external thread (11) on the element (2). The bush pref. has an internal cone (14) to engage the ends (9) of the lips.</p> |
