The attachment device is made of two piece separable construction for use in securing flexible films and fabrics, hereafter referred to as material. One element has two longitudinal grooves facing in opposite directions, one groove being larger than the other groove. The other element has two longitudinal beads that positively interlock with the grooves of the first element when the two elements are pushed together by one of said beads and the larger groove acting as a pivot and the other bead and smaller groove being engageable by relative rotational movement of said elements about said pivot. Flexing of one or both elements allows for engagement of the shallower groove and complementary bead. The said interlocking action of the two elements is utilized to capture and secure material placed between the two elements. The shallower groove and complementary bead are disengageable by relative rotational movement of the two elements about said pivot when the two elements are pulled apart.
