Flexible plastic pipe joint

A soft deformable synthetic resin pipe joint for telescopically connecting a synthetic resinous pipe to a pipe receiving socket comprising:

• said socket including an end portion and a packing holding groove formed on an inner circumferential wall of said socket;
• a packing member held in said groove of said pipe receiving socket and disposed so as to sealingly engage the pipe and the socket and to provide a gap between the inner circumferential portion of said end portion of said socket and the periphery of said pipe inserted therein wherein the outer periphery portion of the end of said pipe forms a chamfered portion, said packing member including a convex outer portion and an a radially inwardly extending compressible portion of smaller diameter than the outside diameter of said pipe;
• a front radially outwardly flared and first and second radially inwardly flared rear inclined walls formed on the inner and outer periphery of said socket to define said groove, said front wall interconnecting with said first rear inclined wall;
• said socket further comprising a supporting portion interconnecting said first and second rear inclined walls, said joint comprising a material of such softness and elasticity that upon external compression of each of said inclined walls, deformation expanding of the gap between said front and first rear walls occurs and inclined faces corresponding to said front and first rear inclined walls are formed on the backing member such that the axis of said pipe is substantially aligned with the axis of said joint upon flattening deformation of said joint.
