To provide a device fitted to a home bathtub for easily and safely attaching and detaching a bathtub plug.

When a piece member 11 is pressed downward while a braid member 3 is pulled by hand, the piece member 11 is connected like a bar to the upper part of the plug 7. The bar-like formed body is manually moved from the outside of the bathtub 5, whereby in addition to the pulling or pressing forces, moment can be applied to the plug 7 at the bottom of the bathtub 5 so that the plug 7 can be easily and safely attached and detached. At this time, the cylindrical body 13A of a presser 13 is lifted horizontally, so that a flange part 33 at the lower end of the cylindrical body 13A and a flange part 31 at the uppermost end of the piece member 11 substantially make right angles to each other, whereby the braid-like member 3 is pulled and the piece member 11 is pressed downward to be connected to each other like a bar.
