A laminate comprising at least one support element in the form of a nonwoven fabric, having a lower face and an upper face, and at least one nonwoven fabric with loops, having a lower face and an upper face, wherein said upper face of the at least one support element in the form of a nonwoven fabric is secured to said lower face of the nonwoven fabric with loops, wherein the laminate is characterized in that the curve representing the force required to stretch the laminate along a given axis of the laminate, as a function of elongation, comprises a segment in which, starting from a zero elongation value, the force increases from zero up to a maximum force, wherein said maximum force corresponds to the rupture of the laminate, and the curve comprises an inflection point (Pi) on said segment wherein the at least one support element in the form of a nonwoven fabric is selected from the group consisting of an SM (Spunbond-Meltblown), an SMS (Spunbond-Meltblown-Spunbond), an SMMS (Spunbond-Meltblown-Meltblown-Spunbond), and an SSMMS (Spunbond-Spunbond-Meltblown-Meltblown-Spunbond); and wherein the non-woven fabric with loops is a carded non-woven fabric, wherein the laminate is characterized in that a top of a zone forming loops or a middle S of a top part, wherein the top part is a flattened top, is offset in a machine direction, with respect to a central point P0 equidistant from the two successive connection zones between which the zone forming loops extends.
