ABSTRACT:
A coupling device for container lashings comprises two tensioning members (1, 3; 11, 13) having coacting teeth (2, 12) and a clamping means (20) for keeping the members with the teeth (2, 12) in mesh. One flank of the teeth (2, 12) inclines at an angle (.alpha.) of between 95.degree. and 110.degree. to the tensional load direction (r) of the member. The other flank of the teeth inclines at an angle (.alpha.) of between 30.degree. and 50.degree. to the tensional load direction (r). The clamping means (20) is an eccentric clamping collar, surrounding the members (1, 11) in their toothed zone and in an open condition affording a clearance (s) between the top land planes of the elements (1, 11) in the same order of magnitude as the tooth depth (t) but in a closed condition the collar (20) maintains the teeth (2, 12) of the members in mesh. Each of the members have means (4, 14) against which a tensioning apparatus (30), e.g. a hydraulic tensioner can be applied.
The collar (20) has an eccentric operating lever (29), the angular attitude of which indicates the closed or open state of the collar (20).
