The invention relates to a segmented packing ring for sealed packages, comprising at least two annular segments (1), which, in the assembled state, are held together in the circumferential direction by means of springs (3). According to the invention, the assembly may be simplified and relatively small springs used as protection against damage as a result of spring breakages, whereby, at each contact point (2) of adjacent annular segments (1), at least one separate tension spring (3) is arranged between anchor elements (5) provided on both ends in the region of the ends (4) of the annular segments (1) and the fixing of the tension springs (3) to the anchor elements (5) has a preferably clip or locking mechanism for single-person operation.
A segmented packing ring comprising at least two annular segments (1) held together in circumferential direction by means of springs (3) in the assembled state whereby at each contact point (2) of adjacent annular segments (1) there is at least one separate tension spring (3) arranged between anchor elements (5) provided on both sides of said annular segments (1), whereby said anchor elements are provided in the area of the ends (4) of the annular segments (1), and whereby fastening of the tension springs (3) occurs respectively on one particular anchor element (5) for each end of the tension spring, and whereby said tension springs are provided with separate fastening elements in the area of both ends, wherein the fastening elements (6) at the end of the tension springs (3) are formed in one piece and connected to the coiled end sections (9) and the center piece (8) of the tension spring (3) by means straight wire sections (7), wherein the anchor elements (5) are formed as recesses (10) on the annular segments (1), and wherein said coiled end sections (9) of the tension spring (3) engage directly into said recesses.
