摘要： PROBLEM TO BE SOLVED: To provide a corrugated pipe joint having such advantages that the number of parts disposed off in connection operation can be reduced or the pipe joint can be re-used by disassembling without cutting the end part of a corrugated pipe after installation. SOLUTION: In this corrugated pipe joint 1, since a retainer holder 31 is slidably positioned at a lock position by a spacer 50 before installation, such an erroneous operation that the retainer 41 is locked before the corrugated pipe T is inserted can be prevented. Since, in the installed state, the retainer holder 31 can be slid to the lock position with the spacer 50 installed between the retainer holder 31 and a body 3, the spacer 50 does not become a waste part in installation. In addition, since, after the installed state, the retainer holder 31 can be slid beyond the lock position to an unlockable state after the spacer 50 is released from the retainer holder 31 and the body 3, the joint 1 can be disassembled without damaging the tip part of the corrugated pipe T.

摘要： PROBLEM TO BE SOLVED: To smoothly perform connection work.
SOLUTION: In a plug-in joint 1 for a corrugated pipe, the corrugated pipe T is inserted into a joint body 10 from a retainer pushing sleeve 50 inner hole, and respective pins 73 are elastically deformed and bent to the inner side when an annular protrusion T' is abutted to the respective pins 73 (pin group) of a stopper 70. At that time, respective split circumferential pieces 75 with which at least a part of a root part of the respective pins 73 is brought into contact is deformed at a root of a ring part 71, and is opened to the outer side. When the annular protrusion T' gets over the inner side of the stopper 70, the pin group of the stopper 70 and the respective split circumferential pieces 75 are recovered to the original state. When the pin group is elastically deformed and recovered to the original state, a worker inserting the corrugated pipe T can feel passing feeling by the sound and/or the touch, and can confirm that the annular protrusion T' passes the stopper 70 by the passing feeling. After the annular protrusion T' gets over the pin group, an outer side of an annular recess T" is surrounded by the stopper 70, and the pin group goes into the annular recess T" and the corrugated pipe is prevented from slipping out until it is fixed.

摘要： PROBLEM TO BE SOLVED: To provide a pressure detection plug and a tool set for the pressure detection plug for preventing the inside of the plug from being exposed carelessly and preventing working efficiency from decreasing in testing.
SOLUTION: An electric outlet adaptor 70 is stored in a storage case 5 of the tool set. Further, a detachable tool 60 is embedded into the opening of the storage case 5. In the detachable tool 60, a circumferential projection 63 at the lower end of a knob section 61 is embedded to a circumferential groove 7 inside the opening of the storage case 5 for mounting, and the knob section 61 also plays a role of the lid of the storage case 5. In this manner, the knob section 61 also plays a role of the lid of the storage case 5, thus dispensing with the lid of the tool set itself. The tool set cannot mount the detachable tool 60 to the storage case 5 while a lid 20 is being sucked to the detachable tool 60, thus for example enabling the lid 20 to be mounted without fail after the lid 20 of the pressure detection plug is removed by using the detachable tool 60 and pressure is detected and air is purged.

摘要： PROBLEM TO BE SOLVED: To provide an insert type pipe joint capable of providing secure sealing by merely inserting bellows pipe into a joint pipe, and having a simple and safe structure. SOLUTION: This insert type pipe joint for connecting the bellows pipe F having recessed and projecting portions 18, 20 in corrugated form on an outer periphery comprises a joint main body 26 in which a pipe insertion aperture 24 for inserting the bellows pipe is formed, and an inner wall surface is stepwise formed; a nut member 30 in the ring shape fixed on a leading end of the joint body; packing members 40, 42 arranged on an inner wall surface of the joint body; and a retainer member 50 in the shape of ring, a leading portion slidably coming into contact with an inner wall of the nut member, the base end being supported to be in contact with the packing member, when the bellows pipe is inserted, the retainer member being applied to the leading end of the bellows pipe, and one portion of the retainer being elastically enlarged and contracted in a radial direction of the bellows pipe, thereby allowing the bellows pipe to be insert into the inside thereof. The nut member is formed with a fallout preventing taper surface 60 which deforms the retainer member in a diametrically contracting direction when a force is exerted to the bellows pipe in a drawing direction. Thus, the bellows pipe is surely sealed and attached by merely inserting it into the joint body.

摘要： PROBLEM TO BE SOLVED: To provide an insert type pipe joint capable of providing secure sealing and attachment by merely inserting a bellows pipe into a joint body, and having a simple and safe structure.
SOLUTION: This insert type pipe joint 16 comprises the joint body 26; a nut member 30 in the ring shape fixed on a leading end of the joint body; packing members 40, 42; a guide member 44 in the ring shape; and a retainer member 50 in the oil ring shape. The retainer member is placed on a housing groove 48 in the ring shape arranged on an outer periphery surface of the guide member at an initial time, and when the bellows pipe is inserted, the retainer is applied to a leading end of the packing member to be pushed out from the housing groove, and it allows the bellows pipe to be inserted into an inside, while elastically enlarging and contracting in a radial direction of the bellows pipe. The nut member 30 is formed with a fallout preventing taper surface 52 which prevents the retainer member from deforming in a diametrically enlarging direction when force is exerted to the bellows pipes in a drawing direction. Thus secure sealing and attachment are provided by merely inserting the bellows pipe in the joint body.
