The present invention relates to a connector attached to a fulcrum end of a pivotal door handle and into which wiring extending from a sensor is introduced, the sensor being built into the door handle to detect a predetermined signal from surroundings, the connector having a contact connected to the wiring. The present invention reliably prevents water from infiltrating into the connector and eliminates the necessity to also replace the door handle when the connector is replaced. The connector includes paired latch arms provided on respective sides of the door handle and which can be installed in and removed from the door handle; and a seal member provided at a port through which wiring is introduced.
