A floor cable channel for positioning a cable line element on an underlying surface and for protecting the cable line element. The floor cable channel includes a first channel element and a second channel element for receiving the cable line element and a connection element connecting the first channel element to the second channel element. The connection element allows a rotational movement of the first channel element relative to the second channel element. The floor cable channel can be brought into a transport position in which the channel elements are parallel to each other and into an operating position in which the channel elements are arranged along their longitudinal axes. In the operating position, the first and second channel elements are in contact at their mutually facing front faces to provide a self-locking of the channel elements relative to each other in the operating position.
