Reexamination Certificate



A U-shaped thermoplastic hair-connecting element is provided with at least one intermediate partition disposed between parallel legs of the U-shaped element. The intermediate partition can be designed as a longitudinal partition which runs essentially parallel to the legs and which projects from a connector of the U-shaped element. Alternatively, the intermediate partition can be a transverse partition which runs essentially transverse to the legs and perpendicular to the connector which connects the legs to one another. There can also be provided longitudinal partitions together with transverse partitions. Foreign hairs can be embedded into the hair-connecting element either during manufacturing, or in a separate manufacturing step.
