Tool for preforming a section of a tubular connector
 A tool for preforming a section of a tubular connector, the connector used for joining two optical fibres in end to end relationship. A plurality of forming members extend radially in a holder and spaced circumferentially around the tubular member support means supports a mandrel in the bore of the tubular member, coaxially thereof, and cams push the forming members radially inward to form a plurality of lobes in the section of the tubular member. The radially inward extremities of the lobes are pushed into contact with the mandrel to define a central bore for reception of the uncoated ends of the fibres. The forming members having a Vee formation with an inclined face at each end of the Vee formation.
