Since the block body 15 is fixed to the optical fiber core 1 by the clamping force of the clamping part 8, if the aforementioned optical fiber core wire connection work is good, the connection strength is sufficient and the resilient member 9 Even if the small rebound force G acts as a tension, the block body 15 does not move to the left or right at all. After the operator visually confirms this, the clamping parts 8, 8
Then, as shown in Fig. 16, (switch 13/push button 13a in Fig. 1 or 2)
) The heater part 6 generates heat, and the heat-shrinkable tube body 3 is heated and contracted to tightly cover the connection part 2 and its vicinity as shown in FIG. 16. In this way, the connection strength testing mechanism 7 is provided to check the strength of the connection portion 2 before heating.

Due to the spring biasing force G, the clamping part 8 moves together with the block body 15 in the direction of arrow a, and the operator can immediately detect a connection failure.
