At least one tension element having two opposite end portions is connected to a closure wall of the lower part and the upper part. Each tension element preferably has a cross section with an overall sinuous shape. A continuously elastic strap section of each tension element has an inner side and an outer side. The inner side has a plurality of inner grooves which are spaced and preferably positioned approximately parallel with respect to each other. The outer side has a plurality of outer grooves which are spaced and preferably positioned approximately parallel with respect to each other. An inner land is positioned between two adjacent inner grooves and an outer land is positioned between two adjacent outer grooves. Along an axis of elasticity of the continuously elastic strap section, each inner groove is positioned opposite a corresponding outer land and each outer groove is positioned opposite a corresponding inner land.
