Claims

[Scope of utility model registration request]

A device for attaching a gas stick to a through hole formed in a wall, a front flange arranged on the front side of the wall around the periphery of the through hole, a back flange arranged on the back side of the wall around the periphery of the through hole, It consists of a tightening screw that is inserted into the through hole and connects both flanges, and by tightening the tightening screw and sandwiching the wall between the front flange and the back flange, the gas tank connected to the front flange can be attached to the wall. The back flange includes a backing ring formed with an external dimension that allows the tightening screw to pass through the through hole with the tightening screw screwed into the screw hole, and the backing ring and the backing ring. It is composed of a plurality of flange pieces held between the back surfaces of the wall body, and these flange pieces hold the flange piece in a position where it can pass through the through hole of the wall body when in the first form, and have a second flange piece. 2. A gasket mounting device characterized by being provided with a member having a shape memory property that moves the collar piece to a clamping position that moves outward from the inner periphery of the through hole of the wall body when the collar piece changes to the configuration of the second embodiment.
