A swivelling joint for use in a pole such as a light pole is disclosed. The swivelling joint connects a first member mounted to a lower leg of a pole with a second member mounted to an upper leg of the pole. The second leg has a skirt which sits around an annular portion of the first member, with a bearing member located between the first and second members. The bearing member can be moved from outside the second member between a locked position where the joint is fixed, and a released position where the joint can rotate. |
