The upper and lower containers C ₁ and C ₂ are connected to each other by engaging with the peripheral portion of the hole H.

By the way, the container connector is composed of the upper and lower containers C ₁ , C.
When connecting _two , or the upper and lower containers C ₁ , C
_When the connection of ₂ is released, it is in a state of being attached to the lower surface of the upper container C ₁ as shown in FIG. 8. At this time, when the lever 36 is rotated, the upper engaging body 34 is rotated, The engagement with the peripheral portion of the engagement hole H is released, and there is a risk that the connector may fall.

As a safety measure, as shown in FIG. 10 and FIG. 11, a protrusion 38 is formed on the outer periphery of a rotary shaft 37 that connects the upper engaging body 34 and the lower engaging body 35, and a flat plate portion is formed on the connector body 30.

Conventionally, there is a coupling tool that prevents the engagement pin 40 from coming off and prevents the lever 36 from rotating to the disengaged position by the engagement between the engagement pin 40 and the protrusion 38.

[Problems to be Solved by the Invention] The above-described connecting tool pushes up the lower end portion of the engaging pin 40 projecting downward from the pin insertion hole 39 and holds the groove 42 at the same height as the projecting portion 38. Since the protrusion 38 can pass through the groove 42, the lever 36 can be rotated to the disengagement position. The rotation of the lever 36 can release the engagement between the peripheral portion of the engagement hole H and both end portions of the upper engagement body 34.

However, in the above-described coupling tool, when the lever 36 is forcibly rotated in the direction in which the engagement pin 40 releases the engagement with the engagement pin 40 preventing the lever 36 from rotating, the protrusion 38 impacts the engagement pin 40. And the engaging pin 40 is deformed. At this time, since the engagement pin 40 is inserted with a small gap that can be slid with respect to the pin insertion hole 39, when the engagement pin 40 is deformed, the engagement pin 40 cannot be slid, and thus the lever. There is an inconvenience that 36 cannot be rotated in the disengagement direction.
