Claim:
A band comprising: a strip portion including a proximal portion, an intermediate portion and a distal portion; engaging means formed on a surface of the proximal portion in one thickness direction thereof; and a plurality of teeth formed in series in a longitudinal direction of the strip portion in at least a portion of the distal portion and the intermediate portion, wherein the strip portion is formed into a ring by bending at least a portion of the strip portion, overlapping a portion of an area from the distal portion to the intermediate portion on the surface of the proximal portion in one thickness direction, and engaging one of the teeth to the engaging means, wherein the ring has a diameter that is configured to be adjusted by selecting one of the teeth engaged to the engaging means, wherein the teeth are formed on opposite sides of the strip portion in a width direction, a plurality of the engaging means are formed spaced apart from each other in the width direction of the proximal portion so as to respectively engage the teeth on opposite sides of the strip portion in the width direction, and a release portion is provided between the engaging means for allowing the portion of the distal portion and the intermediate portion where the teeth are formed to be moved into and out of a space between the engaging means, wherein the proximal portion of the strip portion includes a weakened portion provided between the engaging means, wherein said release portion is configured to allow a part of the band in which the teeth are formed to move in the thickness direction of the band, whereby the part of the band is moved into and out from the engaging means, and wherein the weakened portion is configured to widen the interval between the engaging means.
