<p>PURPOSE:To facilitate the assembly of a movable pipe in a structure where the flexible pipe having a spiral-shaped projection formed on its inner periphery is inserted between a cylindrical main body and a sleeve, by forming a fallable protrusion which falls down when the flexible pipe is inserted and rises when it is drawn out on the outer periphery of the sleeve. CONSTITUTION:This joint which is used for connecting a condiut tube 11 serving as a flexible pipe having a spiral-shaped projection 11a formed on its inner periphery to apparatus on a switchboard or the like has a sleeve 33 unitedly formed on the inside of a cylindrical main body 20. When the conduit tube 11 is inserted into an inserting space 31 formed between the main body 20 and the sleeve 33, the conduit tube 11 is inserted as it pushes down a flexible protrusion 34 formed on the outer periphery of the sleeve 33 to engage the flexible protrusion 34 with the projection 11a in the conduit tube 11 for preventing its slipping out. After fitting the conduit tube 11, the main body 20 and a bushing 28 are relatively rotated to assemble them by ratchet-click engagement between the guide line 26 and saw teeth 27 of a fitting member 25 and a fitting projection 29 and a flat part inside the bushing 28.</p> |
