A positioning tube for an escape slide of the type used for aircraft having a long inflatable ramp which is inflated from the folded condition to the extended position in which the location and attitude of the ramp is controlled by an inflatable tube attached to the underside of the ramp for engagement with the aircraft fuselage to which the ramp is attached for biasing the ramp outward from the fuselage. Manifolding is provided for rapid inflation of the positioning tube simultaneously with inflation of the ramp and before the ramp is completely unfolded and extended. Releasable fasteners of three-dimensional fabric having resilient hook fibers hold the ramp in the folded condition until it is inflated to prevent engagement with the ground prior to inflation and positioning.
