Abstract: An ornamental ceramic fitting is mounted between two spaced, confronting, axially aligned, tubular members. The distance between the confronting ends of the tubular members is less than the corresponding axial length of the ceramic fitting. The ceramic fitting includes a threaded rod extending therethrough along the axis thereof and a well in each end of the fitting surrounding the threaded rod.

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.
