A connector

A hermaphroditic connector 1 comprising a connector body 2 configured for connection to an identical connector body (Figure 2), the connector body having a male part 3 and a female part 4, which have profiles that conform, at least partially, to one another. The male parts may form prongs and an opening 8 may pass through the face of the connector between the prongs. A fastener 13 (Figure 7a) may be passed through the opening. A wire 11 may be received in a recess 9 (Figure 6). The connector may comprise a thermocouple. In a further embodiment there may be a pair of connectors as in Figure 1 and a pair of connectors as in Figure 3, wherein the connectors of Figure 3 cannot be connected to the connectors of Figure 1 because they have different shapes.
