Here, when the locking member 15 moves to the side opposite to the tip of the water pipe 1 inserted into the receiving port 3 a, the removal preventing main body 14 moves the locking member 15 to the outer peripheral surface of the water pipe 1. It has the guide surface 14a which guides so that it may move toward (refer FIG. 4, FIG. 6). In detail, the removal prevention main body 14 is made of, for example, a synthetic resin, and one surface 14 b facing the outer peripheral surface of the water pipe 1 is formed in an arc shape according to the water pipe 1. An accommodation recess 14c for accommodating the locking member 15 is formed on the one surface 14b. And the bottom face of this accommodation recessed part 14c is the said guide surface 14a. Further, one surface 14b of the removal preventing main body 14 functions as the restricting portion 6d, and the restricting portion 6d including the one surface 14b is formed in the housing recess 14c, that is, the locking member 15 (the locking claw 6c). On the other hand, the 1st control part 601 provided in the circumferential direction side (in the illustrated embodiment, both sides in the circumferential direction positioned so as to sandwich the locking member 15) of the water pipe 1 and the tip of the water pipe 1 It has the 2nd control part 602 provided in the side which went to the opposite side from the side, in other words, the anti-packing 7 side (refer FIG. 3). Further, the withdrawal prevention main body 14 is provided with a biasing means that elastically biases the locking member 15 toward the receiving port 3a (that is, the front end side of the water pipe 1 inserted into the receiving port 3a). ing. In the illustrated embodiment, this urging means comprises an elastic protrusion 14d integrally extending from the removal preventing main body 14 and abuts on a protrusion 15c (described later) of the locking member 15 so as to be engaged therewith. The stop member 15 is elastically biased toward the receiving port 3a (see FIGS. 4 and 6).

一方、係止部材１５は、例えば合成樹脂製であって、受口３ａ内に挿入された通水管１の外周面に対向する一の面１５ａが、通水管１に合わせて円弧状に形成されるともに、その一の面１５ａに、係止爪６ｃ、６ｃが突出して形成されている。この係止爪６ｃは、前記通水管１の軸方向に複数（図示実施の形態においては二つ）並んで設けられるとともに、通水管１の周方向に複数（図示実施の形態においては二つ）並んで設けられる。また、係止部材１５の一の面１５ａは、前記規制部６ｄとして機能し、この一の面１５ａからなる規制部６ｄは、係止爪６ｃ、６ｃに対して、通水管１の周方向側（図示実施の形態においては、周方向に並ぶ係止爪６ｃ、６ｃの間）に設けられた第３の規制部６０３、および、通水管１の先端側からその反対側に向かった側、換言すれば、反パッキン７側に設けられた第４の規制部６０４を有している（図３参照）。   On the other hand, the locking member 15 is made of, for example, synthetic resin, and one surface 15a facing the outer peripheral surface of the water pipe 1 inserted into the receiving port 3a is formed in an arc shape in accordance with the water pipe 1. At the same time, locking claws 6c, 6c are formed to protrude from one surface 15a. A plurality (two in the illustrated embodiment) of the locking claws 6c are arranged in the axial direction of the water pipe 1 and a plurality (two in the illustrated embodiment) in the circumferential direction of the water pipe 1 are provided. It is provided side by side. Further, one surface 15a of the locking member 15 functions as the restricting portion 6d, and the restricting portion 6d made of this one surface 15a is on the circumferential side of the water pipe 1 with respect to the locking claws 6c and 6c. (In the illustrated embodiment, the third restricting portion 603 provided between the locking claws 6c, 6c aligned in the circumferential direction), and the side facing from the front end side of the water pipe 1 to the opposite side, in other words If it does, it has the 4th control part 604 provided in the anti-packing 7 side (refer FIG. 3).

そして、係止部材１５は、一の面１５ａとは反対側に位置して、抜脱防止本体１４の傾斜する前記ガイド面１４ａに当接する他の面１５ｂが、そのガイド面１４ａに沿うように傾斜して形成されている。このように、抜脱防止本体１４および係止部材１５を形成することで、通水管１が、接続具本体３の受口３ａから抜け出ようとすると、その通水管１とともに移動する係止部材１５が、抜脱防止本体１４に設けられたガイド面１４ａに案内されて通水管１の外周面に向かって動く。こうして、通水管１への係止爪６ｃ、６ｃの食い込みが的確となり、通水管１が受口３ａから抜け出るのを確実に防止することができる。なお、係止部材１５における一の面１５ａは、通水管１の外周面に沿うよう円弧状に形成されており、他の面１５ｂは、ガイド面１４ａと同様に平面状に形成されている。また、抜脱防止本体１４には、ガイド面１４ａに通孔１４ｅが明けられている。そして、係止部材１５には、他の面１５ｂから突設された突出片１５ｃが設けられている。そして、この突出片１５ｃが抜脱防止本体１４の通孔１４ｅに挿入され、この突出片１５ｃに設けられた係合突部（図示せず）が、通孔１４ｅの周縁に係合する。こうして、係止部材１５は、抜脱防止本体１４に組み付けられるが、このとき、係止部材１５の、通水管１の長手方向への移動を妨げないように、通孔１４ｅは、突出片１５ｃにおける通孔１４ｅ内に留まる部位よりも長く形成されている（図４、図６参照）。   The locking member 15 is positioned on the side opposite to the one surface 15a, and the other surface 15b that contacts the inclined guide surface 14a of the removal preventing main body 14 is along the guide surface 14a. Inclined. In this way, by forming the pull-out prevention main body 14 and the locking member 15, the locking member 15 that moves together with the water flow pipe 1 when the water flow pipe 1 tries to escape from the receiving port 3 a of the connector main body 3. However, it is guided toward the outer peripheral surface of the water flow pipe 1 by being guided by the guide surface 14 a provided in the removal prevention main body 14. In this way, the engaging claws 6c, 6c bite into the water pipe 1 accurately, and the water pipe 1 can be reliably prevented from coming out of the receiving port 3a. In addition, the one surface 15a in the latching member 15 is formed in circular arc shape so that the outer peripheral surface of the water flow pipe 1 may be followed, and the other surface 15b is formed in planar shape similarly to the guide surface 14a. Further, the removal preventing main body 14 has a through hole 14e in the guide surface 14a. The locking member 15 is provided with a protruding piece 15c protruding from the other surface 15b. And this protrusion piece 15c is inserted in the through-hole 14e of the removal prevention main body 14, and the engaging protrusion (not shown) provided in this protrusion piece 15c engages with the periphery of the through-hole 14e. Thus, the locking member 15 is assembled to the pull-out prevention main body 14. At this time, the through hole 14 e is provided with the protruding piece 15 c so as not to prevent the locking member 15 from moving in the longitudinal direction of the water pipe 1. Is formed longer than a portion staying in the through hole 14e (see FIGS. 4 and 6).

この接続具２に通水管１を接続するには、予め、内部に接続具本体３を収容するようにして、ベース体４と被取付体５とを、それらベース体４と被取付体５との間に間隙Ｓを設けた状態で組み合わせておく。このとき、ベース体４と被取付体５とは、ネジ部材１１とそのネジ部材１１が螺合するナット１２により、繋がれているのが好ましい。そして、接続具本体３の各々の受口３ａに、通水管１を挿入する（図４、図５参照）。ここにおいて、ベース体４と被取付体５とに設けられる、係止部材１５は、弾性突片１４ｄによって受口３ａ側に弾性的に付勢されて、抜脱防止本体１４のガイド面１４ａに沿って受口３ａ側に寄った位置に位置して、通水管１の外周面から離れた側にある。したがって、この係止部材１５（係止爪６ｃ）が、通水管１の挿入を妨げることがない。   In order to connect the water pipe 1 to the connector 2, the base body 4 and the mounted body 5 are connected to the base body 4 and the mounted body 5 in advance so that the connecting body 3 is accommodated therein. Are combined with a gap S between them. At this time, it is preferable that the base body 4 and the to-be-attached body 5 are connected by the screw member 11 and the nut 12 to which the screw member 11 is screwed. And the water flow pipe 1 is inserted in each receptacle 3a of the connector main body 3 (refer FIG. 4, FIG. 5). Here, the locking member 15 provided on the base body 4 and the mounted body 5 is elastically biased toward the receiving port 3a by the elastic protrusion 14d, and is applied to the guide surface 14a of the removal preventing main body 14. It is located at a position close to the receiving port 3a along the side away from the outer peripheral surface of the water conduit 1. Therefore, the locking member 15 (locking claw 6c) does not hinder insertion of the water pipe 1.

その後、ネジ部材１１をナット１２に締め付けることで、ベース体４に被取付体５を取り付け固定する（図６、図７参照）。このとき、ベース体４と被取付体５とは、互いに近接して、すなわち、ベース体４に設けられた第１抜脱防止部６ａ（係止部材１５）と被取付体５に設けられた第２抜脱防止部６ｂ（係止部材１５）とが近接して通水管１の外周面を挟む。こうして、通水管１は、この接続具２に接続される。なお、図中符号１６は、通水管１の潰れを防止するためのコア部材であり、通水管１内に、その先端から挿入される。また、この接続具２は、全体がボックス形状（箱型形状）をしており、特に、ベース体４の背面がフラット状に形成されている。そこで、この接続具２は、配管の中継ポイント等において、例えば前もって、ベース体４の背面が設置面に当接するようにして、その設置面にビス等で固定される。そして、その後に、通水管１が、前述の方法で、接続具２に接続される。   Then, the to-be-attached body 5 is attached and fixed to the base body 4 by fastening the screw member 11 to the nut 12 (see FIGS. 6 and 7). At this time, the base body 4 and the attached body 5 are provided close to each other, that is, provided in the first removal preventing portion 6a (the locking member 15) provided in the base body 4 and the attached body 5. The second removal preventing portion 6b (locking member 15) comes close to sandwich the outer peripheral surface of the water conduit 1. Thus, the water conduit 1 is connected to the connector 2. In addition, the code | symbol 16 in a figure is a core member for preventing crushing of the water flow pipe 1, and is inserted in the water flow pipe 1 from the front-end | tip. Further, the whole connecting tool 2 has a box shape (box shape), and in particular, the back surface of the base body 4 is formed in a flat shape. Therefore, the connecting tool 2 is fixed to the installation surface with a screw or the like, for example, in advance such that the back surface of the base body 4 comes into contact with the installation surface at a pipe relay point or the like. And after that, the water flow pipe 1 is connected to the connection tool 2 by the above-mentioned method.

ところで、図８は、接続具２を断熱部材１７で覆う場合を示している。ここで、断熱部材１７は、ベース体４側を覆う第１断熱部材１７ａと、被取付体５側を覆う第２断熱部材１７ｂとから構成されている。また、図示実施の形態においては、断熱部材１７をさらにカバー１８が覆っている。そして、このカバー１８もまた、第１断熱部材１７ａを覆う第１カバー１８ａと、第２断熱部材１７ｂを覆う第２カバー１８ｂとで構成されている。   FIG. 8 shows a case where the connector 2 is covered with the heat insulating member 17. Here, the heat insulation member 17 is comprised from the 1st heat insulation member 17a which covers the base body 4 side, and the 2nd heat insulation member 17b which covers the to-be-attached body 5 side. Further, in the illustrated embodiment, the cover 18 further covers the heat insulating member 17. And this cover 18 is also comprised by the 1st cover 18a which covers the 1st heat insulation member 17a, and the 2nd cover 18b which covers the 2nd heat insulation member 17b.

また、図９は、複数の受口３ａ、３ａの一つに接続アダプター１９を挿入する場合を示している。この接続アダプター１９は、両端が開口する真直ぐな筒形状をしている。そして、接続アダプター１９の、受口３ａに挿入される一方側の外周面には、係止爪６ｃ、６ｃが係合する溝１９ａ、１９ａが設けられている。また、接続アダプター１９の他方側に、通水器具等が連結されるように、外周面にネジ部を備えたテーパ筒状の連結部１９ｂを備えている。   FIG. 9 shows a case where the connection adapter 19 is inserted into one of the plurality of receiving ports 3a, 3a. The connection adapter 19 has a straight cylindrical shape with both ends opened. And the groove | channels 19a and 19a which the latching claws 6c and 6c engage are provided in the outer peripheral surface of the connection adapter 19 at the one side inserted in the receptacle 3a. Moreover, the other end of the connection adapter 19 is provided with a tapered tubular connecting portion 19b having a threaded portion on the outer peripheral surface so that a water passing device or the like is connected.

また、図１０は、複数の受口３ａ、３ａの一つに止水栓２０を挿入する場合を示している。この止水栓２０は、使用しない受口３ａを塞ぐものであり、例えば、一端が閉じた筒形状をしている。そして、止水栓２０の外周面には、係止爪６ｃが係合する段部２０ａが設けられている。   FIG. 10 shows a case where the water stop cock 20 is inserted into one of the plurality of receiving ports 3a, 3a. The water stopper 20 closes the unused receptacle 3a and has, for example, a cylindrical shape with one end closed. And the step part 20a with which the latching claw 6c engages is provided in the outer peripheral surface of the water stopper 20.

次に、以上の構成からなる接続具２の作用効果について説明する。この接続具２によると、抜脱防止部６は、接続具本体３を支持するベース体４に設けられた第１抜脱防止部６ａと、ベース体４に取り付けられる被取付体５に設けられた第２抜脱防止部６ｂとから構成されている。そこで、ベース体４に被取付体５を取り付け固定することで、第１抜脱防止部６ａと第２抜脱防止部６ｂとが、接続具本体３の受口３ａ内に挿入された通水管１の外周面を挟むように近接して、その通水管１の抜脱を防止する。すなわち、第１抜脱防止部６ａと第２抜脱防止部６ｂとが近接することで、それら第１抜脱防止部６ａと第２抜脱防止部６ｂが通水管１の外周面を強く挟み、通水管１は、接続具２に強固に固定される。つまりは、第１抜脱防止部６ａをベース体４に設け、第２抜脱防止部６ｂを被取付体５に設けることで、それら第１および第２抜脱防止部６ａ、６ｂが通水管１の外周面を強く挟み、通水管１を接続具２に強固に固定することができる。   Next, the effect of the connection tool 2 having the above configuration will be described. According to this connection tool 2, the removal prevention part 6 is provided on the first removal prevention part 6 a provided on the base body 4 that supports the connection tool main body 3 and the attached body 5 attached to the base body 4. And a second removal preventing portion 6b. Then, the water pipe which the 1st removal prevention part 6a and the 2nd removal prevention part 6b were inserted in the receptacle 3a of the connection tool main body 3 by attaching and fixing the to-be-attached body 5 to the base body 4. FIG. The water pipe 1 is prevented from being pulled out in close proximity so as to sandwich the outer peripheral surface 1. That is, when the first removal preventing part 6a and the second removal preventing part 6b are close to each other, the first removal preventing part 6a and the second removal preventing part 6b strongly sandwich the outer peripheral surface of the water pipe 1. The water pipe 1 is firmly fixed to the connector 2. That is, by providing the first removal preventing portion 6a on the base body 4 and the second removal preventing portion 6b on the mounted body 5, the first and second removal preventing portions 6a and 6b are connected to the water pipe. The outer peripheral surface of 1 is strongly sandwiched, and the water conduit 1 can be firmly fixed to the connector 2.

さらに、図示実施の形態においては、第１抜脱防止部６ａと第２抜脱防止部６ｂに、通水管１を係止する係止爪６ｃを設けており、この係止爪６ｃにより、通水管１の抜脱に抗する強度を高めることができる。しかも、係止爪６ｃを、通水管１の軸方向に複数（図示実施の形態においては、二列）設けているため、通水管１の抜脱に抗する強度を一層高めることができる。その上、通水管１が、接続具本体３の受口３ａから抜け出ようとすると、その通水管１とともに移動する係止部材１５が、抜脱防止本体１４に設けられたガイド面１４ａに案内されて通水管１の外周面に向かって動く。こうして、通水管１への係止爪６ｃの食い込みが的確となり、通水管１が受口３ａから抜け出るのを確実に防止することができる。   Furthermore, in the illustrated embodiment, a locking claw 6c that locks the water pipe 1 is provided in the first removal preventing portion 6a and the second removal preventing portion 6b. The strength against the removal of the water tube 1 can be increased. In addition, since a plurality of the locking claws 6c are provided in the axial direction of the water pipe 1 (two rows in the illustrated embodiment), the strength against the removal of the water pipe 1 can be further increased. In addition, when the water pipe 1 is about to come out from the receiving port 3 a of the connector main body 3, the locking member 15 that moves together with the water pipe 1 is guided to the guide surface 14 a provided in the removal prevention main body 14. Moving toward the outer peripheral surface of the water pipe 1. Thus, the engagement claw 6c bites into the water pipe 1 accurately, and the water pipe 1 can be reliably prevented from coming out of the receiving port 3a.

また、第１抜脱防止部６ａと第２抜脱防止部６ｂとの内側には、通水管１に対する係止爪６ｃの食い込みを所定量に規制する規制部６ｄが設けられている。このため、通水管１に、横方向等の外力が加わった場合であっても、その通水管１の動きが、規制部６ｄにより止められる。したがって、係止爪６ｃが、通水管１に必要以上に食い込んだり、その食い込みが浅くなったりすることを防ぐことができる。ここで、規制部６ｄは、係止爪６ｃに対して、通水管１の周方向側とか、通水管１の先端側からその反対側に向かった側（通水管１の反先端側）とかに設けられている（詳細には、図３に示すように、係止爪６ｃに対して、通水管１の周方向側に、第１および第３の規制部６０１、６０３が設けられ、通水管１の反先端側に、第２および第４の規制部６０２、６０４が設けられる）。このように規制部６ｄを設けることで、この規制部６ｄが、通水管１の外周面を的確かつ強固に挟み込んで、通水管１の曲がりとか捩れ等に抵抗し、パッキン７にも係止爪６ｃにも、通水管１の曲がりとか捩れ等による負荷がかかるのを防止することができる。特に、規制部６ｄが、係止爪６ｃに対して、通水管１の先端側からその反対側に向かった側（通水管１の反先端側）に設けられる場合には、通水管１の先端側から順に、パッキン７と係止爪６ｃと規制部６ｄとが並ぶこととなり、通水管１を直状に保つことが容易となる。   Further, a restricting portion 6d that restricts the engagement of the locking claw 6c with respect to the water pipe 1 to a predetermined amount is provided inside the first removal preventing portion 6a and the second removal preventing portion 6b. For this reason, even if it is a case where external force, such as a horizontal direction, is added to the water pipe 1, the movement of the water pipe 1 is stopped by the control part 6d. Therefore, it is possible to prevent the locking claws 6c from biting into the water pipe 1 more than necessary or from getting shallower. Here, the restricting portion 6d is located on the circumferential side of the water pipe 1 with respect to the locking claw 6c, or on the side facing from the front end side of the water pipe 1 to the opposite side (the opposite end side of the water pipe 1). (In detail, as shown in FIG. 3, first and third restricting portions 601 and 603 are provided on the circumferential direction side of the water pipe 1 with respect to the locking claw 6c. The second and fourth restricting portions 602 and 604 are provided on the opposite end side of 1). By providing the restricting portion 6d in this manner, the restricting portion 6d sandwiches the outer peripheral surface of the water pipe 1 accurately and firmly, resists bending or twisting of the water pipe 1, and the packing 7 also has a locking claw. It is also possible to prevent the load due to bending or twisting of the water pipe 1 to 6c. In particular, when the restricting portion 6d is provided on the side facing away from the distal end side of the water conduit 1 with respect to the locking claw 6c (the opposite end side of the water conduit 1), the distal end of the water conduit 1 In order from the side, the packing 7, the locking claws 6 c, and the restricting portion 6 d are arranged, and it becomes easy to keep the water conduit 1 straight.

また、被取付体５が、接続具本体３を覆うように形成された一つの被取付体からなることから、その一つの被取付体５に、第２抜脱防止部６ｂの各々が設けられる。したがって、この被取付体５をベース体４に取り付けることで、複数の通水管１、１を一度に接続具２に接続することができる。そして、接続具本体３が、ベース体４と被取付体５とに挟まれて支持されることから、接続具本体３をベース体４と被取付体５とで挟む際に、ベース体４に設けられた第１抜脱防止部６ａと被取付体５に設けられた第２抜脱防止部６ｂとは、受口３ａ内に挿入された通水管１の外周面に向かうようにして互いに近接する。したがって、抜脱防止部が在るところに通水管が挿入される場合とは異なり、通水管１に長手方向の傷が付くことが防止される。反対に、通水管１を接続具２から取り外す際には、ベース体４と被取付体５とを、互いに遠ざけて、ベース体４に設けられた第１抜脱防止部６ａと被取付体５に設けられた第２抜脱防止部６ｂとを、通水管１の外周面から離し、その後、通水管１を、接続具本体３の受口３ａから抜き取ることで、この通水管１の取り外しを容易に行うことができる。   Moreover, since the to-be-attached body 5 consists of one to-be-attached body formed so that the connector main body 3 may be covered, each of the 2nd extraction prevention part 6b is provided in the one to-be-attached body 5. . Therefore, by attaching the attached body 5 to the base body 4, the plurality of water pipes 1, 1 can be connected to the connector 2 at a time. And since the connector main body 3 is supported by being sandwiched between the base body 4 and the attached body 5, when the connector main body 3 is sandwiched between the base body 4 and the attached body 5, The provided first removal preventing portion 6a and the second removal preventing portion 6b provided on the mounted body 5 are close to each other so as to face the outer peripheral surface of the water pipe 1 inserted into the receiving port 3a. To do. Therefore, unlike the case where the water pipe is inserted in the place where the removal preventing portion is present, the water pipe 1 is prevented from being damaged in the longitudinal direction. On the other hand, when removing the water conduit 1 from the connector 2, the base body 4 and the attached body 5 are moved away from each other, and the first removal preventing portion 6 a provided on the base body 4 and the attached body 5. The second drain prevention part 6b provided on the water pipe 1 is separated from the outer peripheral surface of the water pipe 1, and then the water pipe 1 is removed from the receiving port 3a of the connector main body 3 to remove the water pipe 1. It can be done easily.

なお、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、ベース体４と被取付体５とは共通の構成部材からなるが、それぞれが異なる構成部材、すなわち形状とか構造が異なる構成部材からなっていてもよい。   In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, although the base body 4 and the to-be-attached body 5 consist of a common structural member, each may consist of a different structural member, ie, a structural member from which a shape or a structure differs.

また、第１抜脱防止部６ａと第２抜脱防止部６ｂは、抜脱防止本体１４と係止部材１５とからなるが、このうちの抜脱防止本体１４は、ベース体本体１０とか被取付体本体１３と一体に形成されてもよい。また、第１抜脱防止部６ａとか第２抜脱防止部６ｂは、抜脱防止本体１４と係止部材１５との二部品からならなくとも、一部品からなっていてもよい。さらに、第１抜脱防止部６ａとか第２抜脱防止部６ｂは、それぞれ、ベース体本体１０とか被取付体本体１３と、一体に形成されてもよい。   The first removal preventing portion 6a and the second removal preventing portion 6b include a removal prevention main body 14 and a locking member 15. Of these, the removal prevention main body 14 is attached to the base body main body 10 or the covering member. It may be formed integrally with the attachment body 13. In addition, the first removal preventing portion 6a or the second removal preventing portion 6b may be made of one component, instead of the two components of the removal preventing main body 14 and the locking member 15. Furthermore, the 1st extraction prevention part 6a or the 2nd extraction prevention part 6b may be integrally formed with the base body main body 10 or the to-be-attached body 13 respectively.

また、第１抜脱防止部６ａと第２抜脱防止部６ｂの内側には、係止爪６ｃが設けられているが、この係止爪６ｃはなくともよい。   Moreover, although the latching claw 6c is provided inside the 1st extraction prevention part 6a and the 2nd extraction prevention part 6b, this latching claw 6c does not need to be.

また、被取付体５は、接続具本体３を覆うように形成された一つの被取付体からならなくとも、図１１および図１２に示すように、第２抜脱防止部６ｂの各々に対応するように複数（図示実施の形態においては、四つ）設けられてもよい。そして、この場合には、接続具本体３は、ベース体４に、例えばネジ等の固着具２１によりにより、着脱可能に取り付け固定される。図示実施の形態においては、被取付体５は、半円状に形成された第２抜脱防止部６ｂと、その第２抜脱防止部６ｂの各端から横方向に互いに離れるように延びる取付部５ｂ、５ｂとからなる。そして、各々の被取付体５は、その取付部５ｂ、５ｂにおいて、ネジ部材１１、１１とナット１２、１２により、ベース体４に着脱可能に取り付け固定される。なお、第２抜脱防止部６ｂには、係止爪６ｃを設けていないが、勿論係止爪６ｃを設けてもよく、また、第２抜脱防止部６ｂを、抜脱防止本体と係止部材とで構成しても構わない。   Further, the attached body 5 corresponds to each of the second removal preventing portions 6b as shown in FIGS. 11 and 12 even if the attached body 5 does not consist of one attached body formed so as to cover the connector main body 3. Thus, a plurality (four in the illustrated embodiment) may be provided. In this case, the connector main body 3 is detachably attached and fixed to the base body 4 by a fixing tool 21 such as a screw. In the illustrated embodiment, the mounted body 5 includes a semi-circular second removal preventing portion 6b and an attachment extending laterally away from each end of the second removal preventing portion 6b. It consists of parts 5b and 5b. And each to-be-attached body 5 is detachably attached to the base body 4 with the screw members 11 and 11 and the nuts 12 and 12 in the attaching parts 5b and 5b.

また、以上に例示した各接続具２において、ベース体４と被取付体５とは、支持手段Ｘを備えてもよい。この支持手段Ｘは、通水管１を、仮組みされたベース体４と被取付体５との間を通って接続具本体３の受口３ａに挿入可能とすべく、ベース体４と被取付体５とを互いに離れた離間位置に仮支持するものである。図１３〜図２０に、図１〜図１０に示す接続具２とほぼ同様の構造の接続具を例として、支持手段Ｘを設けた接続具２０１を示す。以下、図１〜図１０に示す接続具２と同様の機能を有する構成部分には、同一の符号を付して、異なる部分を主に説明する。支持手段Ｘは、ベース体４と被取付体５との一方から突出する弾性変形可能な突片Ｘ１と、他方に設けられて前記突片Ｘ１を支持する支持部Ｘ２とからなる。そして、ベース体４または／および被取付体５を、前記離間位置から近接する方向に押圧することで、その近接を許容するように、突片Ｘ１が支持部Ｘ２に押されて弾性変形する。詳細には、ベース体４と被取付体５とは、共通の構成部材からなり、それらの一方が反転されて、互いに組み付けられる。すなわち、ベース体４と被取付体５との両方に、突片Ｘ１と支持部Ｘ２とが設けられ、ベース体４に設けられた突片Ｘ１と被取付体５に設けられた支持部Ｘ２とが、支持手段Ｘとしての対を形成し、同様にして、ベース体４に設けられた支持部Ｘ２と被取付体５に設けられた突片Ｘ１とが、支持手段Ｘとしての対を形成する。図示実施の形態においていは、これら支持手段Ｘ、Ｘとしての突片Ｘ１と支持部Ｘ２との対が、各抜脱防止部６の両側に設けられる。具体的には、突片Ｘ１は、ベース体４、詳細にはベース体本体１０（あるいは、被取付体５、詳細には被取付体本体１３）の周壁Ｙから、被取付体５側（あるいは、ベース体４側）に向かって突出して形成されている。そして、突片Ｘ１の、外側を向く側面が、傾斜面Ｘ０１となっている。一方、支持部Ｘ２は、被取付体５、詳細には被取付体本体１３（あるいは、ベース体４、詳細にはベース体本体１０）の周壁Ｙの、先端内方側の角部からなる（勿論、支持部Ｘ２は、角部以外の、周壁Ｙの一部、例えば周壁Ｙの内面等であってもよく、また、周壁Ｙから突出して形成されたものでもよい。）。そして、ベース体４と被取付体５とを仮組みしたとき、突片Ｘ１の傾斜面Ｘ０１が支持部Ｘ２に当接することで、これらベース体４と被取付体５とは離間位置に仮支持される。なお、図中符号２２は、パッキン７を受ける受け部材である。   Moreover, in each connection tool 2 illustrated above, the base body 4 and the mounted body 5 may include support means X. This support means X is connected to the base body 4 and the attached body so that the water pipe 1 can be inserted into the receiving port 3a of the connector body 3 through the temporarily assembled base body 4 and the attached body 5. The body 5 is temporarily supported at spaced apart positions. FIGS. 13 to 20 show a connection tool 201 provided with support means X, taking as an example a connection tool having a structure substantially similar to that of the connection tool 2 shown in FIGS. Hereinafter, the same reference numerals are given to components having the same functions as those of the connector 2 shown in FIGS. 1 to 10, and different portions will be mainly described. The support means X includes an elastically deformable protrusion piece X1 protruding from one of the base body 4 and the attached body 5, and a support portion X2 provided on the other side and supporting the protrusion piece X1. Then, by pressing the base body 4 and / or the mounted body 5 in a direction approaching from the separated position, the projecting piece X1 is pushed by the support portion X2 and elastically deformed so as to allow the proximity. In detail, the base body 4 and the to-be-attached body 5 consist of a common structural member, and one of them is reversed and assembled | attached mutually. That is, the projecting piece X1 and the support part X2 are provided on both the base body 4 and the attached body 5, and the projecting piece X1 provided on the base body 4 and the support part X2 provided on the attached body 5 However, a pair as the support means X is formed, and similarly, the support portion X2 provided on the base body 4 and the protruding piece X1 provided on the mounted body 5 form a pair as the support means X. . In the illustrated embodiment, a pair of the projecting piece X <b> 1 and the support portion X <b> 2 as the support means X and X is provided on both sides of each removal prevention portion 6. Specifically, the projecting piece X1 extends from the peripheral wall Y of the base body 4, specifically, the base body main body 10 (or the mounted body 5, more specifically, the mounted body 13) to the mounted body 5 side (or , The base body 4 side). And the side surface which faces the outer side of the protrusion X1 becomes the inclined surface X01. On the other hand, the support portion X2 includes a corner portion on the tip inward side of the peripheral wall Y of the mounted body 5, specifically, the mounted body main body 13 (or the base body 4, more specifically, the base body main body 10) ( Of course, the support portion X2 may be a part of the peripheral wall Y other than the corner portion, for example, the inner surface of the peripheral wall Y, or may be formed protruding from the peripheral wall Y. And when the base body 4 and the to-be-attached body 5 are temporarily assembled, the base body 4 and the to-be-attached body 5 are temporarily supported in the separated position because the inclined surface X01 of the protrusion X1 contacts the support portion X2. Is done. In addition, the code | symbol 22 is a receiving member which receives the packing 7 in the figure.

この接続具２０１によると、この接続具２０１に通水管１を接続するには、接続具本体３の受口３ａに通水管１を挿入する前に、予め、内部に接続具本体３を収容した状態で、ベース体４と被取付体５とを、例えばネジ部材１１（詳細には、ネジ部材１１とナット１２との螺合）によって仮組みする（図１４〜図１６参照）。こうして、ベース体４と被取付体５とを仮組みしたとき、支持手段Ｘ（詳細には、突片Ｘ１および支持部Ｘ２）によって、ベース体４と被取付体５とは、互いに離れた離間位置に仮支持される。そこで、通水管１を、仮組みされたベース体４と被取付体５との間（詳細には、第１抜脱防止部６ａと第２抜脱防止部６ｂとの間）を通って接続具本体３の受口３ａに挿入する（図１７および図１８参照）。その後、ベース体４と被取付体５とを近接させて組み付ける（図１９および図２０参照）。すなわち、例えばネジ部材１１をナット１２にねじ込むことで、ベース体４と被取付体５とを前記離間位置から近接する方向に押圧する。このとき、ベース体４と被取付体５との近接を許容するように、突片Ｘ１が支持部Ｘ２に押されて内側に向かって弾性変形する。こうして、ベース体４と被取付体５とを近接させて組み付けることができ、この組付により、通水管１は、接続具２０１に固定される。そして、このように、通水管１の接続にあたって、ベース体４と被取付体５とを離間位置に支持した状態で仮組みしておくことで、通水管１を接続具２０１に簡単に接続することができる。   According to this connection tool 201, in order to connect the water conduit 1 to this connector 201, the connection tool main body 3 is accommodated in advance before inserting the water conduit 1 into the receiving port 3 a of the connection tool main body 3. In this state, the base body 4 and the mounted body 5 are temporarily assembled by, for example, the screw member 11 (specifically, the screw member 11 and the nut 12 are screwed together) (see FIGS. 14 to 16). Thus, when the base body 4 and the attachment body 5 are temporarily assembled, the base body 4 and the attachment body 5 are separated from each other by the support means X (specifically, the projecting piece X1 and the support portion X2). Temporarily supported in position. Therefore, the water pipe 1 is connected between the temporarily assembled base body 4 and the attached body 5 (specifically, between the first removal preventing portion 6a and the second removal preventing portion 6b). It inserts in the receptacle 3a of the tool main body 3 (refer FIG. 17 and FIG. 18). Then, the base body 4 and the to-be-attached body 5 are assembled close to each other (see FIGS. 19 and 20). That is, for example, by screwing the screw member 11 into the nut 12, the base body 4 and the mounted body 5 are pressed in the direction approaching from the separated position. At this time, the projecting piece X1 is pushed by the support portion X2 and elastically deformed inward so as to allow the base body 4 and the attached body 5 to approach each other. In this way, the base body 4 and the attached body 5 can be assembled in close proximity, and the water pipe 1 is fixed to the connector 201 by this assembly. And in connecting the water flow pipe 1 in this way, the water flow pipe 1 can be easily connected to the connection tool 201 by temporarily assembling the base body 4 and the mounted body 5 in the separated positions. be able to.

もっとも、前記支持手段Ｘについては、ベース体４に突片Ｘ１と支持部Ｘ２とを設け、被取付体５に、前記突片Ｘ１と支持部Ｘ２とに対向するようにして支持部Ｘ２と突片Ｘ１とを設けてもよいが、ベース体４に複数の突片Ｘ１、Ｘ１を設け、被取付体５に、前記複数の突片Ｘ１、Ｘ１と対向するようにして複数の支持部Ｘ２、Ｘ２を設けてもよく、反対に、被取付体５に複数の突片Ｘ１、Ｘ１を設け、ベース体４に、前記複数の突片Ｘ１、Ｘ１と対向するようにして複数の支持部Ｘ２、Ｘ２を設けても構わない。また、支持手段Ｘを構成する突片Ｘ１は、ベース体４と被取付体５とを近接させるのに伴って弾性変形するように形成されなくとも、ベース体４と被取付体５とを近接させるのに伴って、あるいは近接させる前に、折り取られるものであってもよい。また、支持手段Ｘは、ベース体４と被取付体５とを離間位置に仮支持するようにそれらベース体４と被取付体５との間に配置されて、取り外し可能なスペーサーからなっていても構わない。   However, with respect to the support means X, the base body 4 is provided with the projecting piece X1 and the support portion X2, and the mounted body 5 is opposed to the support portion X2 so as to face the projecting piece X1 and the support portion X2. Although the piece X1 may be provided, the base body 4 is provided with a plurality of projecting pieces X1, X1, and the attached body 5 is provided with a plurality of support portions X2, so as to face the plurality of projecting pieces X1, X1. X2 may be provided, and conversely, a plurality of projecting pieces X1 and X1 are provided on the mounted body 5, and a plurality of support portions X2 are provided on the base body 4 so as to face the plurality of projecting pieces X1 and X1. X2 may be provided. Further, the projecting piece X1 constituting the support means X is not formed so as to be elastically deformed as the base body 4 and the attached body 5 are brought close to each other, but the base body 4 and the attached body 5 are brought close to each other. It may be broken off with or before being brought close. Further, the support means X is arranged between the base body 4 and the mounted body 5 so as to temporarily support the base body 4 and the mounted body 5 in the separated position, and is made of a removable spacer. It doesn't matter.
