Abstract: A network and method of laying network cables in water supply pipes is disclosed. A building is situated near a roadway along which is laid a trunk cable. A water supply pipe branches off the water main to enter the building. A water supply pipe is provided at the time of construction of the building and is an underground pipe.

The connector is pre-produced, such as from relatively rigid material by a moulding operation, and then placed in the mould which is used for producing the bellows. A parison or preform of thermoplastics material is placed in the mould and then blown to form the bellows.
