The rope grab safety device of the present invention releasably attaches a workman's safety belt lanyard to a vertically extending safety rope. The device includes a primary frame assembly constructed of an elongated U-shaped bracket having a pair of spaced apart parallel side plates which is adapted to fit around the rope. A secondary frame assembly also comprised of a pair of side plates is adapted to fit within the U-shaped bracket after the rope is inserted. The secondary frame assembly carries a brake lever and brake shoe which is adapted to engage the rope in the event of a fall. An elongated bent pin connected between the primary and secondary frame assemblies allows for limited pivotal and axial movement between them to thereby allow the rope to be inserted into the U-shaped bracket. A separate locking pin passes through aligned openings in the primary and secondary frame members to secure them together.
