<p>The hinge assembly comprises a first hinge member, having at least one loop forming a pivot hole; a second hinge member, having at least one further loop forming a further pivot hole, and a hinge pivot extending through said pivot holes to pivotally join the first and the second hinge members. The loop of the second hinge member is provided with a transverse hole giving access to the pivot hole and being accessible in the open but not in the closed position of said closure member. In order to avoid having to apply a set screw in this transverse hole to prevent the hinge pivot from being removed by unauthorised persons, the hinge pivot is rotatably mounted in the pivot holes. The hinge pivot is provided with a lateral recess which is accessible, in the open position of said closure member, by a tool inserted through said transverse hole in said further loop to lock the hinge pivot against rotation with respect to the further loop to enable screwing said fixing element on and off the hinge pivot.</p> |
