<p>A hook lock comprises a first locking part (10) comprising ring-shaped element and a second locking part (20) that is provided with a gripping body and a hook finger (22) that can be inserted into the ring element (10), the second locking part having a manually actuatable retaining tongue that extends generally parallel to and in a direction opposite the hook finger (22), the retaining tongue (30), at the free end thereof, having a stopper that engages against a retaining surface (41) of a retaining nose (40), which in the brought together state of the locking parts is situated on the side of the ring element facing the retaining tongue (30), the retaining tongue being turningly biased against the retaining nose. The second locking part (20) carries an arm that extends generally parallel to the retaining tongue (30). The free end (51) of the arm is situated in order to, upon the separation of the locking parts (10, 20), pass over the retaining nose (40). The arm is elastically biased toward the hook finger (22). The arm, which when bringing together the locking parts is turned away from the hook finger (22) by the co-operation with the retaining nose (40), strikes audibly against the first locking part, when the two locking parts come into full engagement with each other.</p> |
