PROBLEM TO BE SOLVED: To facilitate length-shortening work for a watch band. SOLUTION: In this connection structure, a locking member 9 is disposed between outer piece parts 6, 7 that are recessed parts of a connection member and a middle piece part 5 that is a projecting part of the connection member, and a connection pin 4 as a connection member is inserted into a connection hole 8 from the outer hole side with both end parts of a first engagement part 14 pressed to the approaching direction. By separating both end parts of the first engagement part 14 to release stress of the locking member 9, the locking member 9 and the connection pin 4 as the connection member are connected, and the outer piece parts 6, 7 and the middle piece part 5 are connected. When detaching the outer piece parts 6, 7 from the middle piece part 5, the connection pin 4 as the connection member is pushed to the middle piece part direction from the outer hole side with both protrusion parts of a protrusion part 7 pressed to the approaching direction of both the protrusion parts, and a head of the connection pin 4 as the connection member projected from a pin hole is pulled out. Thereby, the locking member 9 is detached, and the outer piece parts 6, 7 are detached from the middle piece part 5.
