A thread-engaging member (7) for a tensioner (1), comprising a body portion (9) of the form of a sleeve and having a threaded interior and a flange portion (8), in which there is further provided a containment component (12) which is arranged to restrict relative movement of the flange portion (8) and the body portion (9) should the flange portion (8) and the body portion (9) separate. Typically, the containment component (12) engages the body portion (9) by engaging the thread of the interior of the body portion (9). The thread-engaging member (7) may also be provided with a weakening (13) arranged so that, if the thread-engaging member (7) is to fail by separating, the failure occurs at all about the weakening (13). |
