A cable entry system includes a length of a grooved pipe adapted for extending through a bore in a wall. A further length of pipe is able to be connected to a rear portion of a socket on an inner side of the wall, with a cap having an aperture through which a cable is able to pass. An additional length of pipe is adapted to be closed by the cap on an outer side of the wall. The cap may be provided with an external circumferential tooth for snapping into a groove of the grooved pipe. In an alternative embodiment, the aperture in the cap is formed by an axially extending slot, which extends through the inner end of the cap, so that the cap may be fitted after installation of the cable. In an additional embodiment, the outer end of the pipe is secured by a C-shaped clip, which engages one of the grooves of the pipe, with the cap being annular and having a central opening defining the axially-facing aperture, and with an inwardly directed circumferential rib of the annular cap adapted for engaging a groove in the C-shaped clip. |
