PURPOSE:To provide a fastener for mounting a hanger of a ceiling or the like to an outer enclosed body wherein ridges and grooves are alternately formed and an engaging part is provided at a point between ridges and grooves, and to make it possible to easily detach the fastener. CONSTITUTION:A fastener 1 has a pair of left and right planar parts 3, each of which has an engaging section 2 on the end thereof, and an arm 5 having a stopper 16 on its end is passed through a right planar part 3b, while guide grooves 19 for allowing a left planar part 3a to slide therethrough are provided on opposite edges of the part 3b. And the engaging section 2 of the part 3b is brought into contact with an engaging section of an outer enclosed body and thereafter the left planar part 3a is caused to side so that the engaging section 2 of the part 3a makes contact with other engaging section of the body, while the arm 5 is rotated to fix by means of the stopper 16. |
