<p>PURPOSE: To provide a supporting body which is not damaged even by the impactive stress, by providing a shoe capable of being moved inside a housing in the prescribed range so that the shoe is split from the housing and detached when the shoe is moved beyond the range. CONSTITUTION: A shoe 3 to hold an overhead cable or wire is inserted in a cylindrical housing 2. The shoe 3 is split into a plurality of pieces when it is detached from the housing 2, and a recess 6 is formed therein. A clamp element 1 is mounted on the housing 2 so as to be oscillated in the prescribed angular range, and a projection formed on a tip is engaged with the recess 6 in the shoe 3. The shoe 3 is freely slidable in the range where the clamp element 1 is oscillated, and when the shoe slides over the range, the shoe 3 is detached from the housing 2 and dropped.</p> |
