Abstract
A towing hook device having a lockable towing hook, use being made for locking of a pivoting pin which has been unilaterally recessed, there being disposed adjacent the recess a drop-shaped body such that the end of a blocking arm of the towing hook causes the blocking pin to execute a forced movement between a blocking position and a release position, the blocking pin in the blocking position being retained by a pawl.

- a frame;
- a towing hook mounted in the frame pivotally about a first axis and having a blocking arm with one end thereof extending from the first axis;
- a blocking member mounted in the frame pivotally about a second axis and having a shaft portion reduced on one side to form an eccentric blocking step which, when the blocking member is in a blocked towing position, abuts the one end of the blocking arm and which, when the blocking member is in a release position, releases the blocking arm and towing hook;
- said blocking member also including an eccentric drop-shaped or comma-shaped body mounted adjacent the reduced side of the shaft portion for co-acting with the one end of the blocking arm when the blocking member is in the release position to return the blocking member to the blocked towing position;
- further said blocking member including at least one concentric locking disc having a latch projection and a limit projection;
