A threadless connection for coupling segments of pipe longitudinally end to end includes a pin end (10) having a groove (18) for receiving therein a locking ring (16). A box end (20) has a groove (19) for receiving the locking ring (16) therein when the pin end (10) is inserted into the box end (20). The locking ring (16) has an uncompressed diameter selected to exert lateral force on the groove (19) in the box end (20) when assembled to the pin end (10).
