A double hubless compression joint for pipes includes a rigid outer retaining sleeve containing an interior resilient sleeve gasket provided with inwardly directed projections on its inner periphery. Prior to the assembly of a pair of end to end pipe sections, the inner diameter of the gasket projections is less than the outer diameter of the pipe sections whereby upon insertion of the pipe ends into the gasket bore, the projections are radially and outwardly displaced against the resistance of the rigid retaining sleeve.
