An ornament for being strung on an elongated member includes a shell having a cavity and a first friction element. The ornament may be arranged in an un-assembled configuration, in which the first friction element is un-attached to the shell, and an assembled configuration, in which the first friction element is attached to the shell. The first friction element has a first retaining part, arranged in the cavity when the ornament is in the assembled configuration, and a first friction part attached to the first retaining part and comprising a first gripping surface for frictionally gripping a surface of the elongated member. The ornament, in the assembled configuration, is strung on the elongated member, and is releasably secured in a first location on the elongated member. The first friction part and the first retaining part have different material and/or mechanical properties in the unassembled configuration.
