A spring actuated engagement device for remotely coupling a movable member to a stationary member comprises a fixture mountable onto a stationary member, a spring biased bar that is axially displaceable within a central recess formed within the fixture, an abutting element extending outwardly from the bar for actuating the spring, and a seating element outwardly spaced from the fixture and longitudinally spaced from the abutting element. The abutting element is axially displaceable in a first direction when contacted by a first edge of a movable member, allowing a second edge of the movable member to be received in an interspace between the seating element and the outer face, and to be axially displaced in a second direction after a force that initiated the contact with the first edge is released. A pivotally displaceable locking device, when set to a locked condition, prevents displacement of the actuator.

The engagement device according to claim 1, wherein the movable member is also transversally engageable by the fixture outer face and the at least one seating element. 3. The engagement device according to claim 1, wherein the guide element is formed with a guiding surface for urging the movable member to a correct lateral alignment when the abutting element is being axially displaced in the first direction if said guiding surface is inadvertently contacted by a portion of the movable member. 4. The engagement device according to claim 1, wherein a spring housing protrudes outwardly from the bar and the spring retained within said housing is attached at a proximal end to a base of the bar and at a distal end to a securing element extending outwardly from a region of the inner face of the fixture which borders the central recess. 5. The engagement device according to claim 4, wherein a positioning element fitted in the base of the bar is adapted to contact an edge of an aperture formed in the inner face, to limit displacement of the bar in the proximal direction. 6. The engagement device according to claim 4, wherein the spring housing longitudinally extends towards the abutting element. 7. The engagement device according to claim 6, wherein a position indicating element extends proximally from the abutting element to define an interspace between said position indicating element and the spring housing for positioning the movable member distal edge when the abutting element is being distally displaced. 8. The engagement device according to claim 7, wherein the position indicating element is formed with an outer guiding surface for urging the movable member distal edge into a correct alignment within the interspace between the position indicating element and the spring housing if the movable element is incorrectly transversally aligned. 9. The engagement device according to claim 1, wherein the fixture has a distal face which extends inwardly from the outer face, a border element being formed within the outer face between said distal face and the central recess to limit distal displacement of the abutting element. 10. The engagement device according to claim 9, wherein the fixture is rectilinear and the distal face is substantially parallel to the proximal face. 11. The engagement device according to claim 9, further comprising a locking device for preventing longitudinal displacement of the abutting element once the movable member is engaged. 12. The engagement device according to claim 11, wherein the locking device is pivotally displaceable and releasably engages the border element when displaced to a locking position. 13. The engagement device according to claim 12, wherein the locking device comprises first and second spaced and substantially mutually parallel elements, an end wall extending between said first and second elements, a handle spaced from said end wall, and a pin extending from a terminal portion of said first element into an aperture formed in the distal face and about which said locking device is pivotally displaceable, wherein, when said locking device is set to the locking position, said first and second elements are sized to engage the border element and said second element is positionable in contact with the abutting element to prevent displacement of the abutting element in a direction between said first and second elements. 14. The engagement device according to claim 13, wherein the distal face has a transversal dimension that is significantly greater than a thickness of the fixture between the inner and outer faces. 15. A method for remotely coupling a movable member to a stationary member, comprising the steps of: a) mounting a fixture of a spring actuated engagement device onto a stationary member, wherein said engagement device comprises a spring actuator that is axially displaceable between an extreme proximal position and an extreme distal position within a central recess formed within said fixture, and at least one seating element outwardly spaced from an outer face of said fixture and proximally spaced from said actuator;b) by a user remotely spaced from said engagement device, manipulating a movable member having a bracket until a distal edge of said bracket is brought in contact with said actuator while a proximal edge of said bracket is spaced from said at least one seating element;c) applying a distally directed force onto said distal edge to cause distal displacement of said actuator and to produce a clearance between said proximal edge and said at least one seating element;d) releasing said applied force until said proximal edge is received in an interspace between said at least one seating element and said fixture outer face and said bracket is rendered substantially immovable as a result of engagement with said actuator and with a surface extending between said at least one seating element and said outer face; ande) preventing axial displacement of said actuator once said bracket is engaged with said actuator and with said surface extending between said at least one seating element and said outer face by displacing a locking device to a locking position such that it releasably engages both said actuator and a border element formed within said outer face which borders said central recess. 16.
