A tubular connector is introduced into one end of the hose via which air can be supplied to the hose. That end of the tubular connector facing the interior of the hose has a flattened configuration and extends in the direction of the longitudinal axis of the hose. The wall of the tubular connector is provided with apertures for the passage of air.
