ABSTRACT:
A clamp for fixing a plant stem to a support wire includes a movable clamp member, a fixed clamp member, a support shaft and a spring attached to the movable and fixed clamp members. Each of the movable and fixed clamp members has a semicircular beak at its one end and an operating member at its other end. The fixed clamp member has an intermediate body portion provided with a support slot for accommodating an intermediate portion of the movable clamp member. The support shaft pivotally attaches the intermediate portion accommodated in the support slot to the fixed clamp member. The spring applies a biasing force causing the two beaks to close onto each other in the manner of a ring and the two operating members to open in a V-like manner. The body portion is provided with slits extending part way along the floor of the support slot from the beak in the direction of the operating member. A notch opening toward the movable clamp member is provided in the floor of the support slot at the location of the inner end of the slits. A protrusion is provided on the intermediate portion for invading the notch when the two beaks are closed under the force of the spring and withdrawing from the notch when the two beaks are opened by a force overcoming the force of the spring.
