TITLE: PIPE COUPLING Abstract of the Disclosure Apparatus for locking together two mutually telescoping tubular members against relative axial movement, the combination comprising; annular bowl means housed within one of the tubular members and including a pair of axially and oppositely tapered annular surfaces; a plurality of gripping elements circumferentially disposed within the annular bowl means, each gripping element includ- ing a pair of oppositely tapered surfaces mateably engaged with respective tapered surfaces of the bowl means; the bowl means and gripping elements being movable between a retracted position in which the tubular members are freely assemblable in the mutually telescoping relationship aforesaid and an extended and locked posi- tion in which the bowl means applies opposing forces against both tapered surfaces of each gripping element to squeeze the latter into tight gripping engagement with the other tubular member whereby both tubular members are locked against relative axial movement, and means for moving the bowl means and gripping elements between the retracted and extended positions.
