A clip 1 has first, second and third clamping elements 4, 6, 18 which are connected together by a common biasing element 2. The biasing element 2 has a flat plate of stainless steel which is folded to form a spring which biases a part 8 of the first element 4 and a part 10 of the second element 6 together to form a primary clamp. The biasing element 2 also biases a part 14 of the second element and a part of the third element 18 together to form a secondary clamp. |
