Tube clamp for securing flexible tube, e.g. hose to rigid tube

摘要

The tube clamp comprises a transversely grooved binding strap (20) having a first end terminating in a head (A) and a second end terminating in a tail (E). A screw holder (1) has hinged clamping plates (3) and is fastened to an opening of the head of the binding strap by its clamping plates and adapted for joining the head and tail of the binding strap. A screw (5) is mounted in the screw holder and turned to move the tail of the binding strap relative to its head in tightening up the tube clamp. The head of the binding strap comprises longitudinal bridging elements (22) disposed at two opposite sides of its opening. Four rounded convex portions are disposed in four corners of the opening and are in contact with a bottom side of the head of the binding strap. Four rounded concave portions are disposed respectively between two opposite ends of the bridging elements and the rounded convex portions at the top side of the transversely grooved binding strap (20) for buffering the pressure of the hinged clamping plates of the screw holder. Four projecting stop portions (220) are respectively and outwardly disposed at two opposite ends of the bridging elements and respectively stopped at two opposite ends of the screw holder.
