PURPOSE: To provide possibility of checking whether a wire is secured in the perfectly fast condition by furnishing No.1 and No.2 contacting pieces which contact the tip of the wire leg in the condition that the wire is in perfectly fast condition, and by installing a continuity sensing means between these contacting pieces.
CONSTITUTION: When the perfectly secured condition is attained, No.1 contacting piece 25 and No.2 contacting piece 26 contact the tips of their respectively mating wire legs 13. When contacting is in effect, the No.1 and No.2 contacting pieces 25, 26 are put in continuity through the wire, that will be sensed by a continuity sensing means 32. In the condition in which the wire is poorly secured, the No.1 and No.2 contacting pieces 25, 26 do not contact the tips of respective legs 13 and remain out of continuity, so that the sensing gives an output of poorly secured condition. This achieves simple and certain sensing of the wire secured condition.
