PURPOSE:To improve the operability by constituting the titled device so that a connecting cylinder and a connector can be detached and attached by one touch. CONSTITUTION:In case each connector has been attached to each end part of a connecting cylinder, when it is placed so as to protrude a little before the middle part of an inserting hole 2, respectively, within a range l in which the tip of a core wire 1a projecting from the front end of a cylinder part 13 of each connector can move backward, each tip of the core wire 1a collides in the inserting hole 2, each of them bends an elastic leg piece of a stopper and moves backward a body and the stopper, a flange 12' is separated a little from the rear end of a cylindrical part 32 of a cover cylinder, always pushed in the direction as indicated with an arrow (a) by a restoring force of an elastic piece 25, and abuts closely. Therefore, when a projecting length of the tip of the core wire from the front end of the cylinder part 13 is made a little longer, even if its length is determined exactly, each tip of the core wire which has been connected is withdrawn a little and always abuts, therefore, a transfer loss of light is not generated.
