Abstract
A safety hook in accordance with the invention comprises a body closed by a pivoting finger which can be prevented from rotating by a transverse locking lever. The locking lever is articulated on a lever pivot on the pivoting finger and has a notch engaging over a front lug of the body in the locked position, into which it is biased by a spring. This assures reliable locking by means of a locking lever that is easy to manipulate.
