Abstract: A strip passing through the object stored in the body, a retaining device for retaining the strip and an actuator with a locking area matching a locking area of one end of the strip. When the actuator is in a locking position, the end of the strip is coupled to the retaining device and when the actuator is in an unlocking position, the end of the strip can be decoupled from the retaining device. The locking area of the actuator has a protrusion and the locking area of the end of the elongated member has a recess for receiving the protrusion. Locking means or mechanisms may be provided for retaining the actuator at least in a locking position.
