Abstract: A mechanical latch (14) for preventing damage to a cable passing through an aperture is disclosed. The mechanical latch comprises a housing (42) adapted to be inserted into an aperture in a first direction and having an internal bore (43) for allowing movement of a cable therethrough. Latch fingers (46) protrude from the housing for engaging an edge of the aperture to prevent removal of the housing from the aperture in a second direction, opposite to the first direction, after insertion of the housing into the aperture in said the direction, to prevent the cable from engaging the edge of the aperture.
