Abstract: A carrier rack for a two-wheeled vehicle, in particular for a bicycle, has a carrying body and struts supporting the same. A lower fastening element is mounted on the struts, and an upper fastening element is mounted on the carrying body for fastening the carrier rack on the vehicle. The lower fastening element can be fitted onto a retaining part, fastenable on the vehicle. It can be brought into operative connection with the retaining part, and released again therefrom, by turning the carrier rack with respect to the retaining part. The upper fastening element is a clamping-type closure which can be manually clamped on, and released again from, a tube of the two-wheeled vehicle. Consequently, the carrier rack can, quickly and easily, be fitted on, and removed from, a two-wheeled vehicle such as a bicycle or mountain bike.

Abstract: A connection coupling or socket arrangement contains two coupling parts each possessing a bore and arranged at an angle with respect to one another. In order to be able to interconnect rods or the like with one another, without the use of further components, the one coupling part serving for receiving one of the rods is continuously lengthwise slotted over the length of its bore. The end regions of this one coupling part bounding at such lengthwise or longitudinal slot each carry a respective portion or section of the other coupling part which is divided into such two portions or sections transversely with respect to its bore. These portions are subjected to the action of a resilient or spring force which strives to mutually shift both of these portions with respect to one another transversely in relation to its bore.
