The invention is designed to detect an incomplete engagement of a connector at an earlier stage. A female connector 10 is formed with a locking arm 13, and a male connector 20 is formed with an engaging groove 23. A short-circuiting fitting 41 is mounted in the lower portion of the locking arm 13, and detection terminals 42 are inserted below the locking arm 13. Accordingly, as the locking arm 13 is deformed at an intermediate stage of an engaging operation, the short-circuiting fitting 41 is moved downward, thereby electrically connecting the detection terminals 42. When engaging projection 13c formed on the locking arm 13 pops into the engaging groove 23, thereby fully engaging the connectors 10 and 20, the detection terminals 42 are electrically disconnected. In other words, by being notified of the intermediate stage of the engaging operation, an operator can determine the completion of the engaging operation earlier.
