    摘要： A shackle has at least one lower end portion received downwardly in a body opening permanently engaged within the body by a split ring within the body expanding and then contracting into an annular groove of the shackle. The split ring is located within the body by a downwardly closed sleeve press fit upwardly into the body opening from a lower end thereof thereby preventing access to the split ring. An annular shoulder on the shackle locates the shackle within the body for such engagement. The shackle may be U-shaped for reception in two body openings or singular ended for one body opening.

    摘要翻译： 卸扣具有至少一个下端部，其在主体开口中被向下收纳，该开口通过主体内的开口环永久地接合在主体内，并且然后收缩到钩环的环形槽中。 开口环通过向下封闭的套筒位于主体内，该套筒从其下端向上压入主体开口，从而防止进入开口环。 卸扣上的环形肩部将钩环定位在主体内用于这种接合。 钩环可以是U形，用于在两个体开口中接收或者以单体结束为一体开口。
