A safety device for steelworkers. The safety device is adapted to be slidably secured about a flanged beam to attach a lifeline to workmen and to secure the workmen against falls. The safety device includes an elongate, preferably bar member having a plurality of apertures therethrough, and first and second L-shaped jaw members suited for clamping about the flange of the beam. The second L-shaped jaw member is slidably affixed to the elongate member by a slide housing attachment portion which includes a barrel portion which allows the elongate member to slidably pass therethrough in a close fitting relationship. The second L-shaped jaw member also includes at least one aperture through the barrel portion. A locking pin is provided which passes through any one of the plurality of apertures in the elongate member, and, and through the barrel portion of the slide housing attachment portion. The locking pin is repositionable from a first, unengaged position to a second, inserted, locking position, so that when in an inserted position, the locking pin interlocks the elongate member and the slide housing attachment portion, to thereby adjustably fix the distance between the first L-shaped jaw member and the second L-shaped jaw member.
