Adjustable clasp for suspending plants

An adjustable clasp for suspending a plant, integrally molded of a semi-rigid polymer material and comprising first and second arcuate arms, said second arcuate arm being longer than said first arcuate arm, each of said first and second arcuate arms having first and second ends and being hinged together at their first ends by means of an integral hinge section of reduced thickness which tends to bias apart the second ends of said arms to form an open position of the clasp, the arms being manually movable around said hinge section to a closed position of the clasp, wherein the second ends of the arms are abutting to form a substantially annular enclosure for encircling a portion of the plant, the arms being secured in said closed position by means of inter-engaging adjustable locking means provided at or adjacent the second ends of the arms, said locking means consisting of a buckle integral with the second end of said first arm and a plurality of integral retaining teeth spacedly provided along an outer circumference of the second end portion of said second arm and pointing obliquely away from said second end, said spacedly provided teeth allowing for adjustment of the clamp size and said teeth also having such length, angle and resilience as to permit irreversible passage of said second end portion of the second arm through said buckle, but prevent its retraction from the buckle with consequent mutual disengagement of the arms and opening of the clasp.
