Abstract
A temple for a spectacle frame has a plug connection between the shaft of the temple and temple end piece first made separately from the shaft of the temple. The plug connection is comprised of a borehole in one of the two elements and a plug on the other of the two elements, which plug is inserted into the borehole, as well as a fixing mechanism for ensuring the relative position between the temple end piece and the shaft. The fixing mechanism has a clamping element, which can assume various axial positions with respect to the peripheral wall surrounding the borehole and which, depending on its axial position, more or less sharply compresses the peripheral wall radially and through this means clamps the plug firmly in the borehole. This design of the fixing mechanism facilitates an exact setting of the length of the temple and of the inner inclination of the temple in adapting it to the geometry of the head of the individual spectacle wearer.
