To even out the contact pressure acting on a catheter when the catheter is fastened and fixed with a packing of a connector. When body-pressing surfaces of A and B members at which a body of the packing is to be pressed come into contact with the body of the packing and the body starts to be pressed, projections of the packing are pressed with a delay from the pressing of the body because of gaps provided between the projections of the packing and projection-pressing surfaces at which the projections of the packing are to be pressed. Thus, the contact pressure acing on the .
