BEFESTIGUNGSVORRICHTUNG ZUM BEFESTIGEN ROHRFOERMIGER BAUTEILE, DURCH DIE EIN FLUID HINDURCHSTROEMT

摘要

A tubular member fixing apparatus having U-shaped clamping member for clamping a tubular member. The U-shaped clamping member has a clamping section at a bottom U portion functioning as confronting clamp walls. The clamp walls have confronting surfaces formed with recessed groove or notched groove. The tubular member is provided with a locking projection engageable with the recessed groove or the notched groove. The locking projection is defined by a radially outwardly buldged portion of the tubular member or a separate annular ring body fixedly attached to the outer peripheral surface of the tubular member. When the tubular member is inserted into the U-shaped clamp walls, the locking projection is brought into engagement with the recessed groove or the notched groove, to thereby ensure fixing of the tubular member to the clamping member.
