A load, traction or similar hook of the safety type has at least one member which has a locking position in which it wholly or partly blocks the interspace between the hook tip and the opposing hook shank or corresponding member. The safety latch is rotatable on an axis which is located substantially in a median plane through the tip and the shank of the hook and is simultaneously axially displaceable along the same axis. The safety latch has an inclined end surface which cooperates with a mating, correspondingly inclined cam surface. The safety latch is biased towards and maintained in a neutral position by a compression spring which maintains said mating surfaces in engagement with each other. |
