The present invention coupling operation is easy, to provide a connection structure which can be firmly connected to the striatum. A Using the connection clip, a structure for connecting the said connecting clip and the striatum, the striatum, constitutes the core wire by a winding which is wound around the core wire, the connecting clip, a main body portion, said and a reduced diameter portion formed continuously in one end of the body portion, said a lockable stopper to the reduced diameter portion of the connection clip, interpolated to the connecting clip, the cylindrical portion of the stopper extending portions near the end portions of the core wire that is inserted, the coupling can be reduced diameter portion of the clip is sandwiched between the stopper is guided to the outside of the clip, the said core wire extends into the reduced diameter portion outside of the clip to in, characterized in that the concatenation of the end of the winding, the connection structure of the striatum. .BACKGROUND
