<p>A joint (12) comprising two parts (14 and 16) which are connected together, which share a common axis (18) and which can be adjusted relative to one another by relative rotation about their common axis (18). The two parts (14 and 16) have inter-engaging formations (64 and 66) which can inter-engage with different relative angular positions between the two parts (14 and 16) about their common axis (18). Resilient means (70, 74, 76, 82) are provided to urge the two parts (14 and 16) towards one another.</p> |
