ABSTRACT:
A tie-back device restrains full extension of an evacuation slide until a predetermined inflation is attained. Inflation of the slide causes tension to be applied to the device. The device comprises two attachment rings and two components which are coupled by a shear pin. A transparent cover is permanently attached to one component. This cover makes the device tamperproof and nonreusable. The cover, in conjunction with the attachment rings and the two components, allows tensile forces to be applied to the shear pin from only one direction.
