Abstract
The invention discloses a marking device for a mould having a housing in a wall. The device includes a threaded cylindrical body and a circular head of a diameter about equal to the diameter of the housing. A face of the head opposite to the body includes structure that turns the head and a marking distinct from the structure and independent from the position of the structure. A length of the body and head are less than the length of the housing in the mould in order that the face with the marking lies flush with the internal face of the wall of the mould when the device is in the housing.
