An apparatus for gripping a support member is described. The apparatus comprises a tubular clamp, the tubular clamp defining a throughbore adapted to receive a support member therethrough, a first apparatus member adapted to engage a first portion of an external surface of the tubular clamp, and a second apparatus member adapted to engage a second portion of the external surface of the tubular clamp. Relative movement of the first apparatus member with respect to the tubular damp in a first direction results in a deflection of a section of a first end of the tubular clamp into the clamp throughbore and relative movement of the second apparatus member in a second direction, opposite the first direction, with respect to the tubular clamp results in a deflection of a section of a second end of the tubular clamp into the clamp throughbore. |
