To provide a coupling device with a simple structure capable of being assembled without using any tool and executing installation of a closed rope easily in a rapid manner.SOLUTION: In a ring holder 4, a lower side of the ring holder 4 is covered by an end part flange 12 at a lower end part of a sleeve 11 that is fixed to a support bolt 6 by a tensile force in an axial direction to be released. At least one locking member 18 for a bolt head part 7 is provided on the ring holder 4 so as to inhibit the bolt head part 7 with respect to the rotation at a locking position and so as not to be engaged with the bolt heat part 7 at an initial position. The support bolt 6 is supported by a ball bearing 9 in a through opening 15 of the ring holder 4. A suspension tool 2 is constructed as an opening ring. Two end part regions of the suspension tool 2 are respectively bent in directions facing each other and respectively extended at the sides facing each other in a radial direction in a recessed part formed in the ring holder 4 which is opened downward in respective cases in an assembled state.SELECTED DRAWING: Figure 3

    【課題】簡単な構造により、工具なしに組み付けることを可能にし、閉じた吊索の設置を簡単且つ迅速な方式で実行できるようする。【解決手段】リングホルダ4は、軸方向の張力によって支持ボルト6に解除可能に固定されるスリーブ11の下端部における端部フランジ12により、リングホルダ4の下側において覆われる。係止位置では回転に関してボルト頭部7を阻止し、且つ初期位置ではボルト頭部7と係合しない、ボルト頭部7のための少なくとも1つの係止部材18がリングホルダ4上に設けられる。支持ボルト6は、玉軸受9によってリングホルダ4の貫通開口15内に支持され、及び吊具2は、開口リングとして構築され、吊具2の2つの端部領域は、互いに向かう方向にそれぞれ屈曲され、且つ組立状態では、リングホルダ4に形成される凹部であって、それぞれの場合に下方向に開口する凹部内に径方向に互いに対向する側において延在する。【選択図】図3
