摘要： PROBLEM TO BE SOLVED: To make a chain of works easily done in cable connection for a cable connection housing body and increase the safety and airtightness and improve an assembly workability remarkably. SOLUTION: In this closure, slits 22 which lead from cable insertion holes to an outside face of an end face plate 3 and which can be cut off are formed in the end face plate 3 and thin caps which can be cut off are installed in the cable insertion holes 20. At the same time, rigidity-preserving sealing members 25 are removably set on the slits 22 and cable insertion holes 20. Furthermore, curved holding pieces 17 which are located face to face with cable insertion recessed sections 16 of a cable holding metal fittings 4 are removably and rotatably installed by pivotal sections 18. Then, free ends 171 of the curved holding pieces 17 are fastened and connected by means of installation members 19. The cable insertion recessed sections 16 and the curved holding pieces 17 are provided with division spacers 33 which are so located that the division spacers of the cable insertion recessed sections 16 and those of the curved holding pieces 17 may face each other. Due to this structure, it is easy to bring junction faces of sleeves face to face with each other and tighten them with tightening tools. Therefore, a cable lead-out, a cable coating, and a cable housing work can be done very rapidly in a cable connection and the very reliable airtightness can be secured in the sleeves.
