    Abstract: A method of installing an optical fibre unit (50) in a joint housing includes push-fit connecting an end to the optical fibre unit to a part (152) of the joint housing that has inlets (155) for optical fibres. The end of the optical fibre unit is push-fit connected with a push-fit connector (162). The other end of push-fit connector is push-fit connected to a mating part (158) of the inlet. The optical fibre unit may be connected at its end to an adapter (164) and push-fit connected with the push-fit connector (162) by push-fit connecting the adapter to the push-fit connector. The optical fibre unit may comprise one or more tubes (52) into which the optical fibres are installed by a blown fibre technique.
