<p>PROBLEM TO BE SOLVED: To connect a corrugated conduit tube simply at low cost without using a connector, by constituting a tube connection part formed out of a tube locking claw protrudingly-formed inward at the circumferential part of a tube inserting hole, and a punch-out part for sealing the tube inserting hole in a way capable of punching out. SOLUTION: A plurality of plate-shaped tube connection parts 4 are formed at the side wall 2 of a wiring box 1. The tube connection part 4, whose outer periphery is of round shape, is formed out of a punch-out part 5 capable of being punched and a pair of tube locking claws 6 protrudingly-formed inward from upper and lower circumferential parts. As a result, in order to connect a corrugated conduit tube to the wiring box 1, first, the punch-out part 5 is punched, the punch-out part 5 is removed at a jointing part 8, and if a corrugated wiring tube is pushed in the tube inserting hole, it is inserted in the tube inserting hole with the protruded part at the front end of the corrugated conduit tube deformed elastically by the tube locking claws 6, and is locked. It is thus possible to connect the corrugated conduit tube with the wiring box 1.</p> |
