The periphery of the recess 50 is a thin wall that is easily elastically deformed, and the engagement groove 46 is elastically deformed and easily spreads. When the engagement protrusion 44 is pressed against the engagement groove 46, the engagement protrusion 44 is elastically deformed to allow the engagement protrusion 44 to pass. When the elastic deformation is restored, the large diameter portion 44a of the engaging convex portion 44 is engaged with the thin wall portion around the engaging groove portion 46 and cannot be pulled out. The recess 50 has a sufficient size to accommodate the engagement protrusion 44. On the inner peripheral surface of the recess 50 intersecting the lower side surface 32e, a step portion 52 is formed at a position apart from the front surface 32f so as to project from three directions toward the center of the recess 50.

  Next, a method of using the slide fastener connector 10 will be described. The slide fastener connector 10 is attached to the slider 18 of the fastener body 16 by elastic deformation. As shown in FIG. 5, the slide fastener connector 10 is held on the front side of the slider 18 where the fastener element 14 is not meshed, and the side edge portion 38 a of the lower portion 38 is formed by the inclined surface 40 on the lower blade of the slider 18. The upper portion 32 is placed on the pull tab mounting portion 24 of the upper blade 20a and pressed firmly to elastically deform to widen the interval between the upper portion 32 and the lower portion 38. When the pull tab attachment portion 24 is located in the through hole 34 of the upper portion 32, the elastic deformation is restored, and as shown in FIG. 6, the attachment of the slide fastener connector 10 to the slider 18 is completed. The straight portion 34b of the through hole 34 of the slide fastener connector 10 contacts the rear side of the pull tab attachment portion 24 of the slider 18 where the fastener element 14 comes out of engagement. The straight portion 34a of the through hole 34 and the connecting portion 36 that communicates with the straight portion 34a abut on the front side of the pull tab mounting portion 24. As a result, the slide fastener connector 10 does not move in the front-rear direction with respect to the slider 18. The side edge portions 34c and 34d of the through hole 34 face the side edge portion in the left-right direction intersecting the front-rear direction of the upper blade 20a and do not move in the left-right direction. A rear end of the upper blade 20a is housed in a recess 37 of the upper portion 32 which is continuous with the through hole 34, and an upper surface 37a of the recess 37 faces the upper blade 20a and a lower portion 38 of the lower blade 38a. It faces 20b and does not move vertically.

  A pull tab 22 is attached to the pull tab attachment portion 24 of the slider 18, and is pulled out from the through hole 34 of the slide fastener coupling tool 10 so that the slider 18 can be moved while holding the pull tab 22. The pull tab 22 does not interfere with the attachment of the slide fastener connector 10 to the slider 18 due to the through hole 34 of the slide fastener connector 10.

  As shown in FIG. 1, two pairs of sliders 18 are attached to the fastener body 16, and the front sides of the fastener elements 14 that do not mesh with each other face each other. The slide fastener connectors 10 are attached to the respective sliders 18, and the front surfaces 32f are used in a state of being opposed to each other. Therefore, the engagement protrusions 44 of the one slide fastener connector 10 face the engagement groove portions 46 of the other slide fastener connector 10.

  In use, when the pair of sliders 18 are brought close to each other and the front surfaces 32f of the slide fastener coupling tool 10 are brought into contact with each other, the engaging protrusions 44 are respectively inserted into the engaging groove portions 46, and the periphery of the engaging groove portions 46 is elastically deformed. As a result, the engagement groove portion 46 expands, and the large diameter portion 44a of the engagement convex portion 44 can pass through. After the large diameter portion 44a has passed and is accommodated in the recess 50, the elastic deformation is restored, and the large diameter portion 44a is engaged and cannot be pulled out. As a result, the pair of sliders 18 are connected to each other as shown in FIG. Even if one slider 18 is moved along the fastener main body 16, the other slider 18 cooperates with each other, so that the meshing of the fastener element 14 does not largely open. When the engagement of the fastener element 14 is released, the pair of sliders 18 are pulled apart with a strong force of a certain level or more to elastically deform the periphery of the engaging groove portion 46 to pass through the large diameter portion 44a of the engaging convex portion 44 and pull out. , Release the connection. Then, when the pair of sliders 18 are moved away from each other, an opening in which the engagement of the fastener element 14 is released is formed between the pair of sliders 18. When the slide fastener connector 10 is unnecessary, the side edge portion 32b side of the upper portion 32 is caused to elastically deform, and the pull tab attachment portion 24 is pulled out from the through hole 34, so that the slide fastener coupling portion 10 can be easily removed.

  According to the slide fastener coupling tool 10 of this embodiment, the pull tab 22 of the slider 18 can be held, the pair of sliders 18 can be brought closer to each other, and the engaging projection 44 can be engaged with the engaging groove portion 46. Can be held and the pair of sliders 18 can be pulled apart to release the engagement between the engagement protrusion 44 and the engagement groove 46, and the engagement and the engagement release operation are easy. Further, it can be attached to the slider 18 of the fastener body 16 by elastic deformation with a simple structure. Further, it can be easily removed when it is not needed, and it can be retrofitted to the existing slider 18, and the shape of the slider 18 does not need to be a special dedicated shape, so that the cost is not required. The pair of sliders 18 attached to the fastener main body 16 can be connected to each other by a simple operation of bringing them into contact with each other. When opening the fastener main body 16, the connection can be released only by pulling the pair of sliders 18 apart with a strong force, and the released sliders 18 can be moved away from each other to open the fastener main body 16. .. Inclined surfaces 35, 40 are formed on the upper part 32 and the lower part 38, and when the inclined surfaces 35, 40 come into contact with the upper wing plate 20a and the lower wing plate 20b of the body 20 of the slider 18, a force acts in a direction of elastic deformation, It can be easily elastically deformed and attached to the slider 18. In particular, when the inclined surface 40 is first brought into contact with the lower blade 20b of the slider 18, a trigger for elastic deformation is obtained, and attachment is easy. The attachment to the slider 18 and the connection between the pair of sliders 18 are both performed by elastic deformation, and a jig, a screw, or the like is unnecessary, which is simple. It is convenient for the user to freely remove the slide fastener connector 10 according to the situation, and the fastener body 16 can be repaired. The slide fastener connector 10 is a single member, and component management is easy. Further, the upper wing plate 20a of the slider 18 is attached so as to make contact with the upper part 32 around the lower wing plate 20b, and the lower wing plate 20b is overlapped and attached to the lower wing plate 20b, which has a wide mounting area with the slider 18 and high mounting strength. . Since the lower portion 38 is provided with the protrusion 42, the protrusion 42 can be brought into contact with the lower blade 20b with high pressure.

  Next, a second embodiment of the invention will be described with reference to FIGS. Here, the same members as those in the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted. The slide fastener connector 60 of this embodiment is integrally formed of a synthetic resin having appropriate elasticity. The slide fastener connector 60 is provided with the upper portion 32 and the lower portion 38 connected by the connecting portion 36.

  At the center of the upper portion 32, a through hole 34 into which the slider 18 is fitted is formed so as to penetrate in the thickness direction. A handle shape cover portion 62 is provided on the upper side surface 32g of the upper portion 32 so as to cover the through hole 34. The handle cover 62 has a dome shape protruding in the thickness direction from the upper side surface 32g of the upper part 32 and is formed integrally with the upper part 32. The shape of the upper surface 62a of the handle shape cover portion 62 which is continuous with the upper side surface 32g and protrudes upward is such that the tip portion is a ridge line extending in the front-rear direction substantially perpendicular to the side edge portion 32a, and the periphery of the ridge line is the upper side surface. It becomes an inclined surface toward 32 g. As a result, the shape of the upper surface 62a of the handle cover 62 becomes a triangular shape with an acute angle when viewed from the side edge 32a or the side edge 32b as shown in FIGS. As shown in c), the shape viewed from the side edge portion 32d is trapezoidal. This is a shape that can be easily picked from both sides of the side edge portion 32c and the side edge portion 32d. As shown in FIG. 9, a lower surface 62b of the handle-shaped cover portion 62 that is continuous with the lower side surface 32e is a plane located parallel to the lower side surface 32e and closes the through hole 34. At the center of the lower surface 62b, a slider recess 62c for accommodating the pull tab mounting portion 24 of the slider 18 for mounting the slide fastener coupling tool 60 is formed. The slider recess 62c is large enough to accommodate the pull tab mounting portion 24.
