A receiving part 8a for an auxiliary leg part 4 is formed on a turning part R. The turning part R turns a predetermined angle by means of the pressing force of the auxiliary leg part 4 acting on the receiving part 8a and created by pressing the leg part 3 of a male part M into an insertion part 1 while the insertion part 1 of the female part F is inserted into an attachment hole Pa for an object P to be attached. An abutted part 2e to a raised part 8b formed on the turning part R is formed on a head part 2 of the female part F, and the female part F moves in a direction that narrows the distance between the turning part R and an engagement part 1b by means of the pressing force of the raised part 8b acting on the abutted part 2e and created by means of the turning movement of the turning part R.
