Tension-preventing means for a pipe plug-in connection

摘要

The invention relates to a tension-preventing means Z for a pipe plug-in connection (S), in particular for a steel socket pipe plug-in connection, in which a spigot (1) of one pipe (R1) is pushed into a socket (6) of the other pipe (R2). In the case of said tension-preventing means, provision is made for an annular body (12) which comprises shells (13, 14), which can be drawn apart transversely with respect to the pipe axis, and engages, on the outside, around the plug-in connection (S) and a part of the spigot (1) which projects out of the plug-in connection (S), and at least one of the shells (13, 14) engages, in a positively locking manner in the withdrawal direction of the plug-in connection (S), behind stop surfaces (5, 10, 11) arranged integrally at the two pipe ends (1, 6), and provision is made for a bracing device for bracing the shells (13, 14) against one another and, if appropriate, pressing the annular body (12) onto the plug-in connection (S) (Figure 1). <IMAGE>
