And a device for coupling the latch device to the security closure, the coupling device comprising or including a flexible strap, wherein the detent device and the latch device are operatively engaged. The closure is positioned so that it is formed into a closed loop, the cooperable engagement with the detent device such that a break in the loop causes visible damage to the closure. , Designed to prevent separation from the latch device. To. Preferably, the latch member is hollow and includes therein a latching device configured to co-operately engage with the detent device, the detent device being insertable for engaging the latching device. It has an opening. As so configured, the cooperable engagement between the detent device and the latch device helps prevent the detent device from being withdrawn from the latch member.

The tag may be omitted if desired, so that there is a direct connection between the latch member and the lock pin. Also, the closed loop formed by the mutual engagement of the detent device and the latch device may be broken by cutting a portion of the loop or by breaking the loop in a weakened area. . As an example, the weak line may be formed at the joint between the lock pin and the tag.

According to another application of the invention, the guarantee device is combined with a docking device for a chuck having two posts which are upright and laterally separated. Each post is provided with a lateral passageway that is sized and aligned with the passageways of the other posts to accommodate the locking pin and extends therethrough. The chuck slider has a lateral opening configured to align with the two passages in the post to accommodate the locking pin when it is closed.
