Abstract
A socket pipe joint includes a male part and a female part in telescopic overlapping position in the joint. An interlocking sleeve member is provided between the male and female parts. Locking elements including the interlocking sleeve member are provided to releasably lock the male part and female part to one another. A locking sleeve is positioned on the male part and extends from a position inside the female part to a position outside an end opening of the female part. A drive assembly is coupled to the locking sleeve on the outside of the joint and is operable to displace the locking sleeve axially between inner and outer positions. A positioning and interlocking element includes a pawl. By axial displacement of the locking sleeve, the pawl is displaced radially, positioning and interlocking the two pipe parts with simultaneous permanent compression of a seal between the pipe parts.
