ABSTRACT Improvements in and relating to Pipe Connectors A pipe connector comprises a tubular pin member having an outer generally frusto-conical peripheral surface provided with annular projections, and a tubular box member having an inner peripheral surface corresponding to the peripheral surface of the pin member, which overlies the peripheral surface of the pin member when the members are fully engaged together, and is provided with annular grooves in which the projections on the pin member are engaged. At the inner end of the peripheral surface of the pin member, the pin member is provided with an annular projection extending in the direction of the free end thereof, overlying the peripheral surface thereof and pro- viding a first radially outer radial surface portion and a second radially inner radially inwardly directed surface portion. The free end of the box member is provided with corresponding radial and radially outwardly directed surface portions. A corresponding projection is provided at the inner end of the peripheral surface of the box member with corresponding radial and radially outwardly directed sur- face portions, the free end of the pin member being pro- vided with corresponding radial and radially inwardly directed surface portions. The pairs of radially inwardly and outwardly directed surface portions are in contact when the pin and box members are fully engaged together, and one of the pairs of radial surfaces are in contact when the members are fully engaged together.
