A tube like member (61) with a first circumferential slit (43) and a second circumferential slit (45). The first circumferential slit (43) has a first end (7) and a second end, the second circumferential slit (45) has a third end (11) and a fourth end (413), the first end and the third end are located on a first radial circumference (400). The first and second circumferential slits provide flexibility to the tube like member. A first bridge (15) is provided extending in a longitudinally direction between the first and the third end. A first longitudinal slit (17) and a second longitudinal slit (19) extend longitudinally along the tube like member. Third and fourth circumferential slits (543, 545) partly overlap with the first and second circumferential slits (43, 45) in the circumferential direction but are separated therefrom by circumferential strips (12, 14).
