<p>A double twistlock to connect adjacent container corner fittings comprises a locking pin rotatable in a housing and comprising a shank which is turned by a hand lever (30) and which carries a transverse locking head (12, 12') at each end. The lock has three positions: the locking position of one transverse head, of the other head, or of both heads. A single spring means (33) is employed which acts between the lever (30) and the locking pin (10), and the housing (20, 20') comprises a locking means (24, 24', 25, 25', 26, 26') to lock the hand lever and hence the locking pin (10) in the three lock positions. The position in which the both heads (12, 12') are locked is the basic position of the lock and any rotation of the locking pin (10) out of this position, to either side, acts against the bias of the spring means (33) to store energy for subsequent automatic locking. <IMAGE></p> |
