The invention concerns a device for controlling the position of points on a part, in particular the position of hole centres made in a part, in particular a sheet metal, comprising a sensor (P) located at the end of a rod (2) for coming into contact with the point or the edge of the hole (t) to be controlled, and means for locating the position of the sensor for deducing the position of the controlled point. The rod (2) bearing the sensor (P) is hinged, in an intermediate zone (6), on a sleeve tube (3) adapted to be removably engaged into the bore (4) of a guide bush (5) set in a reference position, part (16) of the rod opposite the sensor (P) co-operating with means for measuring (M) the displacements of this part (16).
