Abstract
Abstract A pipe coupler has a pair of gripping members with corresponding angularly displaced channels and planar webs. The gripping members are adapted to clasp the pipes between corresponding channels with the gripping members in a spaced apart relationship. Means are also provided for cooperation with the webs to draw the gripping members into closer spaced apart relationship so as to rigidly secure the pipes in the channels.
