Test apparatus for wiring harness body clip

A test apparatus (30, figure 3) is provided for detecting the presence and at least one desired characteristic of a mechanical connector such as a wiring harness body clip (figure 1). The test apparatus comprises a housing (32) having a receiver 34 for receiving and retaining a connector, and a switch 62. A contact element 60 is arranged to move between an open position in which it is spaced from the switch and a closed position in which it operates the switch. First and second mechanical engagement elements 46, 56 are arranged to be engaged by first and second features of the connector respectively when the connector is inserted in the receiver. The contact element is arranged to move to the closed position (figure 8) when the connector is inserted in the receiver. The first and second mechanical engagement elements are arranged to prevent movement of the contact element to the closed position unless the first and second mechanical engagement elements are simultaneously contacted by the first and second features of a connector having a positional relationship corresponding to the correct connector.
