A cable tie includes a band having a first end and a second end a housing, affixed to the band near the second end, with a first opening to receive the first end of the band. The housing comprises a first mass near the first opening and one side of the housing, a stop mass near a second side of the housing, and a second mass between the first mass and the stop mass. When the first end is inserted into the housing, the second mass prevents the first mass from moving a first distance occupied by the second mass, toward the stop mass. When the first end in the housing is being pulled out of the housing, the first mass locks the first end in the housing and prevents the first end from slipping over a second distance.
