The isolator (black cable in from outside, white cable out) should be entirely contained in the white box. The splitter (one cable in, two cables out) is often just left in-line or can be mounted on a skirting board or the wall using the screw holes. There's also a white snap-on cover for it.
Yours could do with some tidying up.
