Claim:
A clamping device for connection comprising: a strap band formed into an open-end annular configuration so as to be tightly wound around a connecting portion to be connected; a housing fixed to one end portion of said strap band in a circumferential direction of said strap band, and rotatably accommodating a worm screw; an array of teeth portion arranged on the other end of said strap band so that said array of teeth portion comes to mesh with said worm screw within said housing, so as to tighten said strap band against said connecting portion by rotating said worm screw against said array of teeth portion; said housing having an outer flat surface connected to another outer flat surface with a curved upper end as a roof portion, right and left sides of which has an arcuately recessed portion to form a slope surface portion as a reinforcement rib on a central portion of said outer flat surface; and said other end portion of said strap band in which said array of teeth portion resides being formed into a wavy and concavo-convex configuration in a width direction of said strap band, so as to increase a meshing area of said array of teeth portion against said worm screw.
