A pipe coupling clamp (1) comprising a pair of clamp halves (2,3) essentially C-shaped in cross-section, and grooved to receive mating flanges of two pipes to be coupled. The clamp halves (2,3) are hinged together at one pair of ends (4,5) by plates (6) and releasably connected together at the other pair of ends (8,9) by a locking eyebolt (10) and associated locking eyebolt nut (11) hingedly connected at its proximal end to the end (9) of one clamp half (3) to allow pivoting moving through an open slot (13) into a securing jaw (14) on the other end (9). The locking eyebolt (10) comprises at its proximal end an eyebolt seating portion (16) connected to a stepped threaded portion (17) of reduced diameter at its distal end. Thus, inlially, on loosening of the nut (11), the locking eyebolt (10) will not disengage within the securing jaw (14) from the clamp (1).
