PROBLEM TO BE SOLVED: To make workload be reduced, and enable an electric wire to be fastened to a pin insulator by a worker itself.SOLUTION: A electric wire fastener 1 includes a first binding-wire part 6 and a second binding-wire part 8 that have approximately U shape and have elasticity. When the first binding-wire part 6 is pressed, in a state that its tip side is made to be engaged with a constriction part 4 of a pin insulator 2 in a manner being hooked, toward the constriction part 4 from a head 3 of the pin insulator 2, it is made to be elastically deformed by the head 3, climbs over the head 3, and then elastically restored in the constriction part 4 to be engaged in the constriction part 4. An electric wire 5 is mounted on an electric wire positioning part 20 provided in the opening end side. The second binding-wire part 8 is in an opening posture until the electric wire 5 is mounted on the first binding-wire part 6, and, after the electric wire 5 has been mounted on the first binding-wire part 6, is made to rotate about the first binding-wire part 6, and be engaged in the constriction part 4 as is the case with the first binding-wire part to come to be in a closed posture where it is overlapped with the first binding part 6. By this, the electric wire 5 is received and held in an electric wire reception concavity 24.SELECTED DRAWING: Figure 4 【課題】作業負担を軽減し、作業者単独で電線をピン碍子に固定できるようにする。【解決手段】電線固定具１は、略Ｕ字形状の弾性を有する第１バインド線部６と第２バインド線部８とを有している。第１バインド線部６は、ピン碍子２のくびれ部４に先端側が引っ掛けられるように係合させられた状態で、ピン碍子２の頭部３からくびれ部４に向けて押し込まれると、頭部３によって弾性変形させられて頭部３を乗り越え、くびれ部４で弾性復元して、くびれ部４内に係合され、開口端側に設けられた電線位置決め部２０に電線５が乗せられる。第２バインド線部８は、第１バインド線部６に電線５が乗せられるまで、開姿勢にあり、第１バインド線部６に電線６が乗せられた後に、第１バインド線部６に対して回動させられ、第１バインド線部と同様にしてくびれ部４内に係合されて第１バインド部６に重ねられる閉姿勢になり、電線収容凹部２４内に電線５を収容・保持する。【選択図】図４
