An object of the present invention is to be installed a trap bundling quickly and easily. Middle portion 42 is pressed against the plate member 21a, and 21b when the force in a direction to approach each other by the intermediate portion 42, 42 the clamping action of the enclosed section 11 [SOLUTION] is applied annular semi-annular member 31a, and 31b semi-annular members 31a and rotating in the direction of arrow Ca, and Ca is restricted, the operation as well is regulated tightened by 31b, the outer plate 21a, 21b the base 2 of the annular region A is stepped on by the object X intermediate part 42 intermediate part 42, 42 semi-annular members 31a, 31b of the are to a relatively high level for 41, 41 ... each end by a pivot shaft 22a is lowered against the end of the , by semi-annular member 31a, and 31b by rotating semi-annular members 31a, 31b as indicated arrow Cb, and Cb plate 21a, for 21b when the 42 is positioned above the respective end portions 41 and 41 and a regulation of the operations to be canceled tightening. [Selection Figure] Figure 7【課題】迅速かつ容易に括り罠を設置可能とする。【解決手段】輪状括り部11の締付け動作によって中間部位42,42を互いに接近させる向きの力が半環状部材31a,31bに加わったときに中間部位42,42が板材21a,21bに押し付けられて矢印Ca,Caの向きへの回動が規制された半環状部材31a,31bによって締付け動作が規制されると共に、対象物Xによって環状領域A内の基部2が踏まれて板材21a,21bの外側の端部に対して回動軸22aが下降させられることで半環状部材31a,31bの中間部位42,42が各端部41,41・・に対して相対的に上昇させられて中間部位42,42が各端部41,41よりも上方に位置したときに半環状部材31a,31bが板材21a,21bに対して矢印Cb,Cbで示すように回動して半環状部材31a,31bによる締付け動作の規制が解除されるように構成されている。【選択図】図7
