Improvements relating to flexible tubing.

摘要

A trunking system is provided for optical fibre cables which will be secured by collar portions 4 carried by strips 1 which are secured to a wall surface by means of a screw passing through a passageway 3. Each strip 1 is formed with longitudinal ribs 6 at both sides which will mate with complementary grooves 8 formed on the inner walls of a continuous trunking sleeve 2. The side arms of the trunking sleeve 2 are flexible so that they can be pushed over the ribs 6 as a snap fit.
