(Image Omitted) The apparatus includes a finger 1 (Fig. 1) which is reciprocable through a row of clamp rings 2 along their axial center line. The clamp rings 2 are asymmetrical and may be positioned in one of two orientations in the row. Each clamp ring has one face which is flat, the other being castellated, the raised portion of the castellated face being relieved and having a chamfer that returns to the base of the castellation. The free end 3 of the finger 1 has a recess 4 in its upper surface which is accurately dimensional to receive a ring 2 (Fig. 2). In the base of the recess but insulated therefrom are two pairs of sensor contacts 5,6 and 7,8 (Fig. 3). A ring 2 in position in the recess 4 connects either the contacts 5 and 6 (Fig. 2) or the contacts 7 and 8, if in the opposite orientation.
