PROBLEM TO BE SOLVED: To simplify the connection structure for suspending a cable or sleeve and improve attaching work of a hook by interposing a hoock which can be stored in the inner position of the tube wall of the simply shaped end tube or in the close position to the inner surface of the tube wall at the connection portions of adjacent simply shaped end tubes. SOLUTION: Mounting a flexible elastic socket 5 on the outer peripheries of the respective end portions of adjacent simply shaped end tubes 1, clamping bands 6 comprising stainless steel plates, etc., are fitted into engagement grooves 5a of the flexible elastic socket 5 from its outside as winding the bands 6 along the grooves 5a to clamp and fasten the bands 6 to the socket 5 by the screwing engagements of bolt screws 6a provided in one-ends of the clamping bands 6. By the clamping bands 6, in the state of interposing a hook 4 between the adjacent simply shaped end tubes 1, the end tubes 1 and the socket 5 are clamped fixedly and integrally with each other to make connectable the adjacent simply shaped end tubes 1. Also, in the state of suspending the sleeve of a cable on a suspending portion 2 of the hook 4, the cable can be inserted easily into the sleeve by the feeding of air thereto, etc. |
