Abstract: A hose clamp has a clamp body, operation pieces, an engaging claw, a receiving portion, an arch shaped opening and a slide guide portion. The clamp body is composed of a plate spring member bent into a ring shape. The operation piece has two legs at one end of the clamp body, and has an operation portion at ends of the legs. The operation piece has a leg at the other end of the clamp body, and has an operation portion at an end portion of the leg. The receiving portion is formed on the operation portion and can engage with the engaging claw. The arch shaped opening is formed on the operation portion, and allows the engaging claw to pass therethrough. The engaging claw and the slide guide portion are disposed on one side of the leg of the operation piece. The slide guide portion contacts with the leg in order to make the engaging claw be opposed to the arch shaped opening.

Abstract: A connector has a pivot shaft extending axially between a pair of flanges of a connector body. The retainer includes a bearing portion at one end, with an expandable insertion slot engageable with the pivot shaft such that the retainer pivots about the pivot shaft. The retainer has a temporary engagement position where a pipe can be inserted and removed and a regular engagement position where a bulge portion of the pipe is engaged preventing the pipe from being removed. A stopper claw formed on an opening edge of the insertion slot contacts with a contact surface, preventing the connector body from pivoting beyond the temporary engagement position. This prevents a condition here the retainer further pivots past the temporary engagement position which can cause the insertion slot to expand and the retainer separating from the pivot shaft.

Abstract: An inlet hole capable of inserting a pipe thereinto is formed in a pipe joint body along an axis. Retainer attaching holes for attaching with a retainer that prevents detachment of the pipe are formed in a side surface of the pipe joint body to extend therethrough. These retainer attaching holes are configured symmetrically with respect to an X axis passing through a center of the inlet hole as a symmetrical axis. Thus, a circumference of the inlet hole opens symmetrically, so that the heat shrinkage condition after molding is equalized in the circumferential direction. Accordingly, it is not necessary to process a molding pin for the inlet hole with imbalance of heat shrinkage amount in mind, so that the molding pin becomes easy to process. In addition, the retainer can selectively utilize the retainer attaching holes at two positions, so that selective use depending on installation environment can be achieved.

Abstract: A pipe joint for connecting a rigid pipe with a retaining flange to a tube includes a pipe joint body formed with a through bore and a window in communication with the bore. A tube connector portion may be connected at an angle to a rigid pipe connector portion. A pipe retainer provided with locking pieces can be located in two positions relative to the pipe joint body. The first position allows the retaining flange to pass through the locking pieces. The second position retains the rear of the retaining flange and prevents inadvertent removal of the rigid pipe. The retaining pieces engage the rear of the flange through the window communicating with the bore. The locking direction of the retainer can be altered relative to the tube connector portion to suit different applications and ease assembly.

Abstract: An erroneous assembling preventing tool for a universal joint prevents a shaft from being fixed to a cylindrical section of a yoke main body of the universal joint by fastening a bolt in a state where the shaft is not inserted into a normal position of an axial direction of the cylindrical section. The erroneous assembling preventing tool comprises a fixing section fixed to the yoke main body, a prevention section arranged between first and second tabs of the yoke main body, and a driving section for driving a prevention section. The prevention section is displaceable to a prevention position at which an end of the bolt can be prevented from being inserted through a screw hole of the second tab of the yoke and a prevention release position. The driving section displaces the prevention section to the prevention release position when it is pressed by an end of the shaft inserted into the normal position of the axial direction of the cylindrical section.

Abstract: A hose clamp includes a clamping body formed by bending a band-shaped spring plate into a generally circular shape flexibly deformed into a contracted state and a spread state. The clamping body is attached to a hose before the hose is connected to a pipe. A holder is mounted on the clamping body to hold the clamping body in the spread state in which the clamping body is loosely fitted with an end of the hose. The holder releases the clamping body from the spread state so that the clamping body is deformed into the contracted state in which the clamping body clamps a junction of the hose and the pipe. A positioner positions the clamping body at the end of the hose, the positioner including a clamp retainer attached to an outer circumference of the clamping body and a locking element which engages the hose to prevent the clamping body from displacing axially and circumferentially with respect to the hose.

Abstract: A hose clip for clamping a hose includes a clamping body formed by bending a band-shaped spring plate into a circular form. A frame-shaped first grip is formed at one end of the body so as to protrude radially outward, and a second grip is formed at the other end of the body so as to protrude radially outward and so as to oppose the first grip when moved through an inside of the first grip. A locking protrusion protrudes from the first grip toward the second grip, and a locking opening is formed in the second grip so as to be engaged with the protrusion. When the protrusion engages the locking opening, the first and second grips are held close to each other such that the body is held in a spread state. The protrusion disengages from the locking opening when the first and second grips are displaced radially relative to each other.

Abstract: A pipe fitting includes a slider disposed in an insertion hole of a main body so as to be axially moved and includes a pressed portion which a falling-off preventing flange of a pipe abuts so that the slider is pressed axially when the pipe is inserted into the insertion hole. A fitting checker includes a pair of spreading legs having respective claws, the fitting checker being detachably attached to the main body so that the legs hold the main body. The claws engage the body and the slider so that the fitting checker is not allowed to be detached from the body when the legs are closed. The legs are spread so as to release the claws from engagement with the body and the slider so that the fitting checker is allowed to be detached from the body. Releasing protrusions are formed to protrude from inside portions of the legs of the fitting checker, the releasing protrusions being pressed so that the legs are elastically deformed in respective opening directions.

Abstract: A holding member (1) for holding a pipe (P), and a mounting member (2) for fixing the pipe (P) to a body panel (B) are previously connected together by a thin connecting portion (9). The holding member (1) and the mounting member (2) in the integrated state are set in a forming die. The connecting portion (9) is collapsed with the closing of such the die that the holding member (1) and the mounting member (2) are separated from each other. A coupling member (3) is formed in this state. Accordingly, the working efficiency can be improved as compared with the case where the holding member and the mounting member are individually set in the die. The holding member (1) and the mounting member (2) are coupled together by the coupling member (3). Since the coupling member (3) is formed of a rubber material, vibration caused in the pipe (P) can be prevented from being transferred to the body panel.

Abstract: A hose clip of the self-holding type includes a clamping ring made by circularly bending a band-shaped leaf spring. A first knob is formed by cutting off a central portion of the clamping ring at a side of its first end in a predetermined range of its length to obtain a groove-like opening and by raising the end of the clamping ring radially. The first knob includes a generally arch-shaped portion. A second knob includes a narrow portion at a side of the second end of the clamping ring, and os formed by fitting the narrow portion into the opening and passing under the arch-shaped portion of the first knob and by raising the second end of the clamping ring radially with respect to the clamping ring so that the second knob confronts the first knob. An abutment face is formed on a surface of the arch-shaped portion of the first knob opposed to a surface of the arch-shaped portion confronting the second knob.
