METHOD AND APPARATUS FOR COUPLING PIPE OR THE LIKE ABSTRACT OF THE DISCLOSURE Method and apparatus for connecting the ends of pipes or the like. The apparatus includes a pair of coupling members, each being mountable at one end thereof to the end of one of the pipes which are to be connected. One of the coupling members has attached at the other end thereof an annular outwardly extend- ing flange having forward and rearward sides. The flange is preferably dovetailed in cross-section. The other member is provided with a housing for receiving the flange in mating and locking engagement therewith. A plurality of cam members are carried by the housing and are radially movable between a retracted position in which the flange is receivable by the housing and an extended position in which the cam members are engaged with the rearward side of the flange to drive it into locking engagement with the housing. Means are also provided for releasably tying or interlocking the housing to the other coupling so as to prevent undesired radial outward deformation of the housing upon actuation of the cam members when the two coupling members are coupled together. Means such as hydraulic cylinder assemblies are also provided for moving the cam members between the retracted position to the extended position to accomplish the aforesaid joining and interlocking of the coupling members.
