A breakaway pipe coupling for coupling a pipeline together comprising a pair of telescopingly engaged upper and lower tubular coupling members adapted to be connected to a pipeline and including a pair of flanges surrounding the members for holding them in fixed relationship, one flange being secured to the upper coupling member and a split flange surrounding but not secured to the lower coupling member. Frangible bolts secure the upper flange portion to the split flange with the split flange adapted to separate when undue stress is placed on the coupling members and breaks the frangible bolts.
