The invention relates to an infant or adult diaper, having a first and second elastic cuff (30a, 30b) being positioned on either longitudinal side of the topsheet (22) and opposing each other, the longitudinally extending elastic cuffs (30a, 30b) each having a proximal edge (32) being attached to the diaper and each having a distal edge (34), at least the crotch region (B) of which is not attached to the diaper (10) and forms a free flap (38a, 38b) wherein the diaper (10) comprises a cuff connector (70) being attached to the first longitudinally extending elastic cuff (30a) and to the second longitudinally extending elastic cuff (30b), the cuff connector (70) extending in a generally transverse direction and being able to extert a force between the longitudinally extending elastic cuffs (30a, 30b) wherein the cuff connector (70) comprises a cuff connector material and the cuff connector material:- has a transverse strain of about 0.8 at a first cycle extension force of about 1.0 N or less, as measured according to the in-use two-cycle hysteresis test and- has about 30% set or less after having been extended to a transverse strain of about 0.8, as measured according to the in-use two-cycle hysteresis test and- is elastically extensible in the transverse direction to a strain of at least about 0.8, as measured according to the in-process two-cycle hysteresis test at 22°C
