A device for locating a shackle lock on a bicycle frame is composed of a first member, a second member, a locking member, and a third member. The first member has an axial hole engageable with a bicycle frame tube such that the first member can be turned in the range of 360 degrees. The second member is joined with the first member by the locking member such that the second member can be adjusted in the range of 360 degrees on the locking member serving as an axis, and that the first and the second members are fastened securely with the bicycle frame tube when the locking member is tightened up. The third member is fastened with one end of the shackle of the shackle lock for locating the shackle lock on the second member.
