うにしたことを特徴とする管材の連結装置。 A lever body has a tube material having a pair of opposing engagement holes formed at the diameter position of the end portion, and a substantially U-shaped elastic plate curved into a substantially semicircular shape along the outer peripheral surface of the tube material. A lever having a pair of opposing engagement protrusions and a slit extending across the end of the lever body on the outer circumferential side of these protrusions, and a connecting plug main body having an outer diameter that fits into the inner circumferential surface of the pipe material. a connecting plug having a tapered truncated conical portion formed at the end thereof and an annular groove formed near the end of the main body of the connecting plug, the engaging protrusion of the lever being rotated into the engaging hole of the pipe material; When the lever body is movably engaged and the lever body is placed along the outer circumferential surface of the tube material, the engaging protrusion protrudes from the inner circumferential surface of the tube material and engages with the annular groove of the connecting plug fitted into the tube material, raising the lever body. A connecting device for pipe materials, characterized in that when the center portion of the main body is brought into contact with the outer circumferential surface of the pipe material, the engaging protrusion is retracted toward the outer circumferential side of the pipe material.
