The half-boxes 1-A, 1-B are opened and cover a connection wire bundle B wired to a building material from front and rear, left and right sides, or the upper part. A check plate or a valve is inserted so as to position in the lower part of the connection wire bundle B, and in the position corresponding to the size of the connection wire bundle B, the projection formed at the end of one half-box is locked to a locking hole formed at the end of the other half-box for fixing.
