The tension biases the second tag end into the open position.

Abstract: A security seal has a housing and a hasp moveable relative to the housing in a first direction between a locked position and a unlocked position. The hasp, in the locked position, is lockable to the housing by a disposable seal. The housing has an opening to allow the insertion of the disposable seal in a second direction different from the first direction. The hasp includes a first locking element engageable, in the locked position, with a second, matching locking element of the disposable seal to prevent movement of the hasp in the first direction toward the unlocked position and withdrawal of the disposable seal in the second direction. The hasp is attached to the housing so as to be both slidable and pivotable relative to the housing.

Abstract: The invention concerns a tamper-evident padlock and padlock combination. The padlock (10) has a moulded plastics lock body (14) which includes an open-ended passage (22) and an opening (26) spaced from the passage. There is also a hasp (16) which has first and second spaced apart legs (32, 34). An end (32.1) of the first leg can be located in the passage through a first end thereof while the end of the second leg can be located simultaneously in the opening. The end of the first leg in the passage can then be engaged by a breakable seal (20) which is inserted into the passage through the opposite end of the passage, in order to lock the hasp relative to the lock body. The padlock combination (12) comprises the padlock (10) and the seal (20) in combination.

Abstract: A pressure-sensitive locking device comprises a housing (2,20) having an opening therein, and an insertable member (1,21) adapted to be inserted into the opening whereupon it can enter into locking engagement with a locking member (4,36) in the housing. The locking member (4,36) is cooperable with a pressure-sensitive mechanism (7,28) in the housing to effect disengagement between the locking member (4,36) and the insertable member (1,21) upon a reduction of pressure.

Abstract: A robust rigid block forming a fastener and tamper evident seal attaches a cover to a tote bin. The seal is formed partially into a C-shaped locking device for insertion into aligned bores in the tote bin cover and bin. The C-shaped device is inserted to an insertion position and then displaced to a locking position with the legs of the device overlying the cover and bin members at the bores fastening the cover to the bin and capable of withstanding high shock loads. A locking element connected to the device by a frangible web has a camming surface that engages an edge of the cover for camming the device during insertion of the element in the bores to the insertion position at which time the web is fractured. The element has a flange plate attached to the element body by a weak web for selective removal of the plate. A resilient tang is attached to the element for engaging a mating locking recess in the body for locking the element to the device and to the bin and cover in the insertion position.

Abstract: A padlock concept consisting of a novel shackle comprised of two tapered shackle elements arranged so that they overlay each other to enclose and opening sufficient to accept the staple of a hasp or attachment device. The shackle elements are connected at one end and when unlocked and unlatched are free to move apart, in a motion causing the two shackle elements to separate, providing a clearance between them, at the unconnected end. Each shackle element includes an opening to allow the staple of the hasp to pass to the common opening. This clearance occurs in opposing elements so that when the elements are brought together or closed the staple of the hasp is completely enclosed by the two shackle elements which substantially fill the space available within the hasp staple. The elements are then latched and locked to provide the security function of a padlock engaged with the staple of a hasp or attachment device.

Abstract: A locking device prevents a rod for closing a door of a container or truck from being rotated in an unlocking direction so as to keep the container doors locked, even if a control handle of the rod should be cut. The rod has is provided near the surface of the door so as to be rotatable about its axis into and out of engagement with door closing members fixed on the container body. The locking device has a first locking member mounted on the control handle at a base portion thereof, a second locking member mounted at a position opposite to the first locking member across the control handle, and a fixing member for inseparably fixing the second locking member to the first locking member. The second locking member prevents the rotation of the rod in the unlocking direction by abutting the surface of the door when the second locking member and the first locking member are inseparably coupled together around the control handle.
