<p>There is a need for a fluid pipe anchor gasket that exerts a reduced radial force on a spigot end inserted into a pipe socket. An anchor gasket (10) according to the invention includes an annular, elastomeric member (15) having secured therein a series a metal segments (11). The segments each have a concave portion (11a) on their upper sides. Each concave portion terminates in a contact point such as a cusp (13) that is of low height. This allows the metal segments (11) to pass under a bead (19) formed in the socket member, whilst maintaining positive engagement of the teeth (12) of the metal segment with the spigot end. This reduces the radial force, applied to the spigot by the teeth, whilst retaining an adequate axial force sufficient to prevent the pipes from separating in use.</p> |
