PROBLEM TO BE SOLVED: To provide a device for performing fixture coupling by extending members pivotally connected to each other such as pivotally-connected frames of a folding bicycle, which can realize the fixture coupling only by extending the members. SOLUTION: The device includes: a first fixture member 20 provided in an end 10-1 of a first member 10; a first locking member 22 provided in an end 12-1 of a second member 12 and equipped with a locking part 22-5 which is engaged with/disengaged from the first fixture member when the first member is at a position where it is extended (that is, where the ends of the first and second members are made to abut against each other); an urging means 23 which urges the first locking member so that it moves from the unlocking position to the locking position; a lock member 24 for the locking member which is attached to the second member in such a manner that it can displace between a fixture position where the first locking member is fixed at the unlocking position and a release position where the first locking member is allowed to be at the locking position, the lock member being normally held at the locking position; and a fixture release member 30 which is attached to the first member so as to displace the lock member for the locking member from the fixture position to the release position when the first member is at the abutment position.
