A work bag or travel suitcase with an incorporated extendable pull handle and with wheels includes a framework, having a practically parallelepiped shape and with an outer covering, in a lower portion of whose frame a supporting and containment element for a pull handle is constrained at one side having a greater length and lesser width, which is situated at the end of rod elements which can be extracted from the supporting and containment element, a pair of wheels being arranged in an opposite position with respect to the pull handle and with both the supporting and containment element and the extractable rod elements have a flattened telescopic form and are made of a light and particularly resistant material, also to shear and flexural stress. A particular pulling device which can be applied to a work bag or travel suitcase is also envisaged.
