An operation to press closure medical tube can be performed quickly and reliably, providing medical tubing clamp a novel structure.
The first plate-shaped portion provided in each of opposing surfaces of the compression projection for closing the medical tube (12) (22, 24) (14) and the second plate-shaped portion in the (16), from the one to the other side walls projecting provided with a (41, 41), provided with a central guide projection projecting toward the one from the other (48, 48). Further, the tip portion sides of the central guide projection (48) inclined guide surface projecting toward the center and (46), the first plate portion (14) and the second approach plate-shaped portion (16) direction when clamping the medical tube (12) by relative displacement, horizontal displacement side walls (41, 41) and the inclined guide surface of the first plate-like portion (14) and the second plate-shaped portion (16) (46 , it is fixed in the slip with 46), a central guide projection (48, 48) is so inserted between both side walls (41, 41).
