Patent ID: 8347669

Claim:
A securing system comprising a securing mechanism and a device that is to be secured, the securing mechanism having a closing part and in which at least two locking elements are rotatably mounted that are designed for an engagement into an annular groove of the device that is to be secured, each of the locking elements having an engaging element to lock the device that is to be secured in any position of rotation of said each locking element except one position of rotation of said each locking element defined by a recess to allow unlocking, wherein an end region of each of the locking elements is accessible from outside the closing part to allow an adjusting member to engage therein, wherein a spring is assigned to each of the locking elements, wherein said spring presses the respective locking element in the direction of the axis of rotation thereof against a contact area of the closing part, and wherein a catching structure having a plurality of catching recesses is disposed on a surface of each of the respective locking elements, wherein an edge of the annular groove of the device that is to be secured forms a catching element, which engages into the catching recesses of the catching structure when the device that is to be secured is attached to the securing mechanism and the respective locking element is rotated at least when the closing part is tilted or axially displaced, wherein the spring acting upon the respective locking element presses the engaging element against an annular surface of the contact area of the closing part, wherein a surface of the engaging element facing the contact area of the closing part is provided with the catching structure and wherein each of the catching recesses has a surface similar to the recess that allows the unlocking of the respective locking element but is only a few tenths of a millimeter deep.
