摘要： A reusable security tag has an enclosure containing an element detectable by independent means and a cruciate sheet metal clutch lock. A pin for piercing a garment is secured at the end of a lever arm which is hinged to said enclosure for controlled movement into said clutch lock. Said pin is released from said clutch lock by application of a special tool to said enclosure for deforming said clutch lock to spread its jaws. Elliptical grooves around the shank of said pin increase the retentivity of said clutch lock without decreasing unnecessarily the tensile strength of said shank. This is a division of application Ser. No. 428,827, now U.S. Pat. No. 3,942,829 filed Dec. 27, 1973.
摘要翻译：可重复使用的安全标签具有包含可通过独立装置检测的元件和十字形钣金离合器锁的外壳。用于刺穿衣服的销被固定在杠杆臂的端部，该杠杆臂铰接到所述外壳上，用于受控地移动到所述离合器锁中。所述销通过向所述外壳施加专用工具从所述离合器锁释放，用于使所述离合器锁变形以扩展其钳口。所述销的柄周围的椭圆槽增加了所述离合器锁的保持性，而不必不必要地减小所述柄的拉伸强度。
