The clamp (10) consists of two semicircular portions (1,2), hinged together (51) at their first ends (101,201) and held by a screw bolt (3) at the second ends (102,202). One end of the bolt is hinged (52) to one of the ends, and the other end is forked to allow the threaded end (31) of the bolt and the nut (32) to be swung into place.
