A strap for towing a wheeled suitcase, passing through a slit in an end wall of the suitcase, is retractable into a housing adjoining that wall from within and containing a coil spring whose free end is coupled with that strap, advantageously through a roller or other deflecting member around which the strap is looped inside the housing. The free outer end of the strap is secured to a handgrip by having holes traversed by pins on a backing plate integral with that handgrip, the front of this strap end being covered by a flap which may be an integral extension of the backing plate folded around the strap and clamped in position with a snap fit. The backing plate has two rearwardly projecting lips which enter the slit of the suitcase wall in a retracted position and are separated by a gap traversed by the strap, these lips passing between ribs of a shield plate that penetrate the slit and engage the housing.
