ABSTRACT:
The invention provides a pair of bodies with operative faces that can be brought face to face. The operative face of one body is formed with a row of circular openings of uniform diameter and spaced uniformly apart. The operative face of the other body has a row of locating formations which may also comprise a row of circular openings similar to those in said one body. The openings and formations are together such as to define a passageway for receiving and locating a helical wire of pitch equal to the spacing between the centers of the openings in said one body. The helical wire can be advanced axially relative to the bodies by rotating it about its own axis.
