理解される。When connecting the plug 1 and the socket 2, the plug 1 is inserted into the socket 2,
In this case, the plug 1 is fitted into the socket 2 while being pushed open by the elastic taper portion 8 of the spring ring 7 while being guided by the guide taper portion 4, and when the elastic taper portion 8 reaches the locking groove portion 5. As shown in FIG. 2, the elastic locking portion 8 is elastically locked in the locking groove portion 5 for connection. Further, in this state, the small diameter portion 13 at the tip of the plug 1 is fitted into the small diameter hole portion 15 of the socket 2 and the O-ring 19 is provided at the small diameter portion 1.
The outer periphery of 3 is elastically intimately adhered to provide a seal. By the way, in this case, when the plug 1 is not completely fitted in the socket 2 and the fitting depth is shallow, the elastic locking portion 8 is not elastically locked in the locking groove portion 5. However, the elastic locking portion 8 is locked from the outside by the locking groove portion 5.
It is not possible to confirm whether or not it is elastically locked to the, and if the elastic locking portion 8 is not elastically locked to the locking groove portion 5, a poor connection will result. In the state where the plug 1 is fitted in the socket 2 and the elastic locking portion 8 of the spring ring 7 is locked in the locking groove portion 5 of the plug 1, the plug 1 is fitted in the socket 2 and the spring is engaged. Since the elastic locking portion 8 of the ring 7 cannot be locked in the locking groove portion 5 of the plug 1 by providing the locking tool 30 which cannot be engaged with the socket 2 in the shallow fitting depth of the plug 1,
If the plug 1 is not inserted deeply until the elastic locking portion 8 of the spring ring 7 is locked in the locking groove portion 5 of the plug 1, the locking tool 30 cannot be locked and the spring ring 7 It can be easily confirmed that the elastic locking portion 8 is not locked in the locking groove portion 5 of the plug 1. That is, in the embodiment shown in FIGS. 1, 2, and 3, the engagement is not performed until the elastic engagement portion 8 of the spring ring 7 is elastically engaged with the engagement groove portion 5 of the plug 1 at the insertion depth of the plug 1. The stopper 30 is moved forward so that the female screw portion 32 can be screwed into the female screw portion 36 of the socket 2. Thus, the locking tool 30 is the engaging portion 37 and the female screw portion 36 of the socket 2. It can be confirmed that the elastic locking portion 8 of the spring ring 7 is elastically locked in the locking groove portion 5 of the plug 1 as shown in FIG. When 30 cannot be engaged by being screwed into the female screw portion 36 of the socket 2 which is the engaging portion 37,
As shown in FIG. 3, it can be seen that the elastic locking portion 8 of the spring ring 7 is not locked in the locking groove portion 5 of the plug 1, and the operator understands that the plug 12 needs to be pushed all the way in again. To be done.

Then, the bent corner of the tip bent portion 17 at the tip of both legs 9 of the spring ring 7 rides on the edge of the lower end of the kerf 6, and the both legs 9 spread, whereby the elastic locking portion 8 is locked. Since it is disengaged from the groove 5, the plug 1 can be easily pulled out from the socket 2 by pulling out the plug 1 in this state. In this case, the spring ring 7 may be pulled out completely.

続することができるものである。As described above, according to the present invention, the locking groove is provided in the rear portion of the cylindrical plug, and the wall of the cylindrical socket is provided with the cut groove that opens inside and outside the socket. A substantially U-shaped spring ring that is inserted into the cut groove from the outside of the socket across the socket is provided, and the portion of the spring ring inserted into the cut groove is inserted into the socket from the cut groove and elastically locked. Since the elastic locking part of the spring ring is locked in the locking groove part of the plug inserted in the socket, the elastic locking part is elastic in the locking groove part just by inserting the plug in the socket. The connection is made by locking to, and one-touch connection is possible. Moreover, such a structure for one-touch connection is a structure in which the groove is formed in the cylindrical socket and the spring ring is inserted from the outside of the socket, and the structure is simple and the assembly is simplified. Is. Also, it can be engaged when the plug is fitted in the socket and the elastic locking part of the spring ring is locked in the locking groove part of the plug. Since there is a locking tool that cannot be engaged at a shallow fitting depth of the plug into the socket that cannot be locked in the locking groove, the elastic locking part of the spring ring should be locked in the locking groove of the plug. If the plug is not inserted deeply until it is inserted, the locking tool cannot be locked and it is easy to confirm that the elastic locking part of the spring ring is not locked in the locking groove part of the plug. As a result, the plug can be reliably connected to the socket.
