1. A moulded article obtained by injection moulding of a material, the article comprising a main body having a body volume which is defined by the space within a main body outer surface forming an outer envelope, and a field of hooks formed integrally with the main body of the moulded article, each hook having a stem with a longitudinal axis and a hooking part which projects laterally from the stem, wherein: the moulded article is made from thermoplastic material;the total volume of the hooks forming the field of hooks is between 100,000 and 100,000,000 times smaller than the body volume of the main body;the width, or smallest transverse dimension of the stem, measured transversely to the longitudinal axis, is smaller than the thickness of the main body, measured along the longitudinal axis of the stem;the main body and the field of hooks form a single piece obtained by a single injection moulding step, the article having no interface in the material;and the moulded article further comprises on an outer surface at least one area in the form of a hollow or point, corresponding to an opening at a point of injection of the material during manufacture by injection moulding of the moulded article, where the surface of the moulded article opposed to the field of hooks is devoid of such area. 2. A moulded article according to claim 1, wherein the field of hooks covers strictly less than half the main body outer surface. 3. A moulded article according to claim 1, wherein the largest height dimension of at least one hook of the field of hooks, measured along the longitudinal axis, is smaller than the thickness of the main body measured along the longitudinal axis of the stem. 4. A moulded article according to claim 1, wherein the width of the base of the stem of at least one hook of the field of hooks, which is its smallest dimension transversely to the longitudinal axis, is less than 0.29 mm. 5. A moulded article according to claim 1, wherein at least one hook of the field of hooks has a size or height smaller than 0.9 mm. 6. A moulded article according to claim 1, wherein the field of hooks covers less than 30% of the main body outer surface. 7. A moulded article according to claim 1, wherein the width of the base of the stem of at least one hook of the field of hooks, which is its smallest dimension transversely to the longitudinal axis, is between 0.05 and 0.15 mm. 8. A moulded article according to claim 1, wherein at least one hook of the field of hooks has a size or height between 0.2 mm and 0.7 mm.
