An apparatus comprising first and second elements and a connecting element is provided. The first element comprises a first terminal member, an intermediate member having first and second ends, and a second terminal member having a closed form channel. The connecting element goes through the channel thereby engaging the first and second elements. An axis connects the first terminal member and the intermediate member first end permitting a closed position, in which the first terminal member adjoins the intermediate member, and an open position, in which the first terminal member is away from the intermediate member. Another axis connects the second terminal member and the intermediate member second end permitting a closed position, in which the second terminal member adjoins the intermediate member, and an open position, in which the second terminal member is away from the intermediate member. The second element retains an object.
