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. Removal of the plate by fracturing the web permits the element to be released releasing the device. Different embodiments are disclosed employing hook shaped tangs which are released by a weak web, J-shaped detents and other arrangements including seals with somewhat differing insertion modes into the tote bin openings.

1. A seal and fastener for securing together a plurality of members with aligned bores comprising:a locking device with opposing spaced legs, the device for insertion in a first direction into the aligned bores for securing the members together in a locking position in which position the device legs are juxtaposed with a portion of the members; and a locking element for insertion into the aligned bores of the members adjacent to the device for locking the device in the locking position; the device being arranged and constructed so that the device is first inserted to an insertion position in the first direction and is then displaced in its entirety from the insertion position to the locking position in a direction transverse to the first direction in response to the insertion of the element.
