A clamp 101 comprises a flexible strap 102, the strap fabricated from a first plastic material and having a plurality of longitudinally spaced teeth 103 and a housing 105. The clamp further comprises a worm screw 108 configured to engage with the teeth of the strap. The housing 105 is configured to receive the worm screw 108 and an end of the strap such that the diameter of the clamp is adjustable by rotation of the worm screw. The worm screw may be fabricated from a second plastic material, which may be acetal. The first plastic material may be nylon. The clamp 101 is configured such that when the plastic strap 102 is engaged within the housing 105, a plurality of the teeth 103 are disposed to mesh simultaneously with a plurality of turns 401 of the worm screw. A method of manufacturing the clip, comprising first and second moulding operations to mould the strap and worm screw from first and second plastic materials respectively is also disclosed. |
