PROBLEM TO BE SOLVED: To detect the condition in which a wire can be extracted, when releasing wire connection. SOLUTION: A terminal block is composed of a terminal plate 130, formed by bending a metal plate so as to face both end parts on both sides of its central part 130a to each other, and a lock spring 131 retained between both the end parts. A wire insertion hole 114 for inserting a wire between the terminal plate 130 and the locking spring 131 is bored in a body 1 for receiving the terminal block, and a release button 115 for moving a lock part 131a of the locking spring 131 for locking a conductor wire of the inserted wire, in response to the depression thereof to move it in a direction of separation from the terminal plate 130 is integrally formed in the vicinity of the wire insertion hole 114. A moving projection part 115a is formed integrally in the release button 115, and a fixed projection part 116 is formed integrally ahead of the movement of the moving projection part 115a with the body 11. Sense of clicking is imparted, when the wire connection is released.
