Each lug has a groove formed on the underside of the lug in the lateral direction with respect to the band, an opening of the groove having a smaller width than a width of the groove. A band has a pair of cylindrical portions forming a recess there-between. A connecting pin comprising a solid pin and a hollow pin slidably mounted on the solid pin is engaged with the cylindrical potions of the band. The solid pin has a small diameter portion which is able to pass the opening of the groove. Each of the solid pin and the hollow pin has a large diameter portion which is engageable with the groove and is unable to pass the opening.
