たことを特徴とするねじなしカツプリング。 It has a nearly cylindrical metal body that has an opening extending over its entire length parallel to the axis, and a pair of grip parts formed by bending both side edges of this opening toward the outer periphery. and a grip case that slides and engages the pair of grip portions while sandwiching them, and a blade portion that bites into the outer periphery of the two pipes to be connected that are inserted into the body from both sides. and a plurality of locking pins protruding from the inner peripheral surface of the body, the mounting hole passing through the body in the radial direction includes an equal diameter hole portion and an inner circumference of the body of the equal diameter hole portion. The lock pin is provided with a cylindrical portion and a conical hole that extends from the cylindrical portion and expands in diameter toward the inner periphery of the body. A trapezoidal portion and a blade portion that is connected to the large diameter end of the truncated conical portion via a step and has a smaller outer diameter than the large diameter end are sequentially formed from the outer circumferential side to the inner circumferential side of the body, and Fit the cylindrical part and truncated conical part of the lock pin into the equal diameter hole part and the conical hole part of the mounting hole, respectively, and engage the locking part raised from the inner circumference of the body with a punch to the step of the lock pin. A screwless coupling featuring a locking pin fixed to the body.
