The induction ring (10) is adapted for removably surrounding a pipe and is provided with two arcuate frames (14, 16) hingedly connected in end to end circumferential relationship, these frames having a pair of connected free ends adapted to be opened for placing the frames around the pipe. A plurality of electrically conducting wires (32) (Fig. 2) are carried upon the frames across the axial width thereof and extend cicumferentially between the free ends. An electrical coupling assembly comprises a male connector (60) including two projections (74) adapted to be received in two corresponding holes (88) (Fig. 5) in the female connector (62), each connector being provided with a plurality of coil contacts (76, 90) each connected to an end of a wire, each of the coil contacts of one connector being received in a recess containing a resilient O-ring (93) whereby, when the male and the female connectors are placed in an interfitting relationship, the coil contacts of the male connector are held resiliently against the coil contacts of the female connector to provide electrical continuity for the thus-connected wires. <IMAGE> |
