Abstract: A cord retaining and fastening device having a housing with opposed passages through which two cord sections are disposed. A clamping element is removably secured in the housing between at least converging open sections of the passages and is biased towards converging open sections of the passages to clamp one or both of the cord sections when the cord sections are pulled in the biasing direction of the clamping element. When the cords are pulled from the passages, in an opposed direction to the biasing direction, they are free to move out of their respective passages.

Abstract: An adapter device for interconnecting a drivable element to a drive, such as a ratchet or an impact tool. The device comprises a body having a connecting shank protruding therefrom. The shank has an automatic lock for locking engagement in a cavity of a drivable element. The automatic lock has a roller bearing displaceable in a bearing cavity formed in a flat wall of the shank. The bearing cavity has an angulated roller guide wall on which the roller bearing is displaced to position the roller bearing to an engaging and disengaged position. A spring biased linkage is connected to the roller bearing to normally bias the bearing to the engaging position. The body is further provided with a locking cavity further having an automatic locking element whereby to connect the body to a drive to impart a motion to the connecting shank.
