Patent ID: 7524131

Claim:
A detachable locking arrangement comprising: a push-in element; a receiving member having an insertion opening structured and arranged to receive therein the push-in element; a locking device which is removably insertable into a clearance area of the receiving member; the clearance area being defined by a space arranged between the push-in element and an inner surface of the receiving member when the push-in element is inserted in the insertion opening; the locking device preventing removal of the push-in element from the receiving member when the push-in element is inserted within the insertion opening and when the locking device is inserted into the clearance area, thereby defining a locked position; the receiving member comprising a stop mechanism which engages the push-in element so as to prevent the push-in element from moving out of the insertion opening; the push-in element being prevented from moving further into the insertion opening along an insertion direction after being inserted in the insertion opening; and further comprising at least one of: a projecting shoulder arranged on the receiving member for preventing the push-in element from moving substantially along an insertion direction after the push-in element is inserted within the receiving member due to contact of an end surface of the push-in element against the projecting shoulder; or inwardly projecting guideways arranged on the receiving member for guiding movement of the locking device; wherein the locking device is movable between an engaged position where it is locked with the receiving member upon insertion and a released position where it is disengaged from the receiving member, and includes a reusable spring member that is releasably engageable to the receiving member, and the spring member includes a locking projection extending outwardly at a free end thereof that engages in an opening in the receiving member automatically upon insertion into the clearance area and is externally releasable via an inward pressure applied to the locking projection or spring member.
