An object of the present invention is to provide a connecting device that can complete the connection in one movement and that will never come loose once connected.

[Means for Solving the Problems] In order to achieve the above object, the connecting device according to the present invention has two opposing members each having an inclined surface having a predetermined slope on its outer surface, and a plurality of A contact am formed of serrated protrusions, and two elastic legs are formed in a U-shape so as to sandwich the connection part, and the slope of the connection part on the inside of the legs is almost the same as that of the connection part. The stopper includes a serrated projection formed on a sloped surface to engage with the serrated projection of the connecting portion.

Further, an uneven portion was formed in the connection portion to prevent mutual movement of the members.

[Function] In the connecting device configured as described above, the two legs of the stopper formed in a U-shape can be pushed in between the connecting portion made of two members having serrated projections. Ba,
The serrations formed on the inside of the legs of the stopper engage with the serrations formed on the outer surfaces of the two members of the connection part, and the stopper will not come off from the connection part if this condition is maintained.

When removing the stopper from the connection part, open the two legs of the stopper, and since the legs have elasticity, the legs will open accordingly and the stopper can be removed from the connection part.

In addition, by providing uneven parts on the two members of the connection part,
The two members will no longer be misaligned.

is the flange, (13) is the serration, (14) is the uneven part, (15) is the stopper, (16) is its leg, (17)
is a serration.

In the figure, a ring (lO) is a connecting part (12) formed by a ring part (11), a wall surface (12a) and a flange (12b) that are erected across a slit (lla).
Therefore, the ring (11) is elastically urged to open outward. On the outside of the wall surface (12a) of the connecting portion, a sawtooth projection (13) is formed on a light slope with a predetermined slope α1, and an uneven portion (14) is formed on the flange (12b).

The stopper (15) is formed in a U-shape with two elastic legs (16), and serrations (17) are formed on the inside of the legs (16) on a light slope with a slope of α2. ing.

The slope α1 of the connection part (12) and the slope α2 of the inside of the leg of the stopper are almost the same, and the serrations (17) formed on the stopper are the same as the serrations (13) of the connection part (12).
It is something that meshes with.

The uneven portion (14) also allows the connecting portion (12) to be connected to the stopper (1).
This is to prevent the flange (12b) of the connection portion from shifting in the direction of the arrow (18) when tightened in step 5). The connecting device according to the present invention is configured as described above.

Using the above connection device, for example, as shown in Fig. 2,
When attaching the gas hose (5) to the gas main valve (6),
The hose (5) surrounding the ring (11) is attached to the main stopper (6), and the stopper (15) is pushed into the connection part (12) of the ring. The leg portion (16) of the stopper (15) has elasticity, and its slope α2 is approximately the same as the slope α1 of the connection portion (12).
) is inserted smoothly between the legs (18), and the distance d between the flanges (12) of the connecting portion (12) becomes small. When the stopper (15) is fully pushed into the connection part (12), the elasticity of the legs (1θ) of the stopper (I5) causes the wall surface (12a) of the connection part to approach, and the ring (
Step 11) is to tighten the gas hose (5) to the gas main valve (6) so that the two are firmly attached. At this time, the serrated protrusions (17) of the stopper (15) engage with the serrated protrusions (13) of the connection part, and as it is, the stopper (15) will not fit into the connection part (12).
You can't get out of it.

When removing the stopper (15) from the connection part (12),
Just open the legs (16) of the stopper and pull it out.

When the connecting device according to the present invention is used, the stopper (15)
Since the parts can be connected in one motion by simply pushing the parts together, the connection does not take much effort, and the engagement of the serrated projections prevents the connection part from loosening after connection. The connection part (12) does not shift,
This ensures extremely reliable connection of parts.

Note that the shapes of the sawtooth projections (13) and (17) in this embodiment are not particularly limited, and may be of any shape as long as it achieves the desired effect.

The slope of the connection part and stopper should also be determined appropriately according to the specifications of the connection device.
