The tie assembly for bundles of cables, pipes, or ropes includes a block and a strap 24 for anchoring by one end to the block, the block having a passage 12 therethrough for reception of the strap 24 and at least one knife-edge protrusion 22 projecting into the passage 12 and being directed towards a face 14 of the block to bite into a length of strap 24 located in passage 12. As shown, block has two parallel passages 12 and first end of strap 24 may be received in one passage and the strap is then looped around bundle and the free end of strap inserted in other passage 12. Block may be moulded from hard-fibre reinforced thermo-plastics material with integral knife edge protrusions or they may be formed by metal inserts. Figures 3, 4 illustrate modifications - with knife edges close to front face 14, and passages opening into opposite faces (26, 28). Strap may be moulded integrally with block, there then being only one passage. <IMAGE> |
