A support member for supporting a mortar shell ( 1 ) into a barrel ( 2 ) of a weapon, and a method for attaching said supporting member ( 6 ) to a tail ( 4 ) in the mortar shell ( 1 ). The supporting member ( 6 ) includes a support element ( 8 ) provided with a rim flange ( 7 ) and a firing mechanism ( 15 ). The support element ( 8 ) is supported by means of one or more attachment pieces ( 10 ) against a front rim ( 23 ) in guiding fins ( 5 ) in the mortar shell ( 1 ). The attachment pieces ( 10 ) include a predetermined deformable point enabling the detachment of the fired mortar shell ( 1 ) from the supporting member ( 6 ).

1. A support member for supporting a mortar shell into a barrel of a breech-loading weapon, the support member comprisinga support element including a rim flange and a firing mechanism for firing the actual primer of the mortar shell,at least one attachment piece for attaching the support element to at least one guiding fin disposed at the tail of the mortar shell,the attachment piece including at least one longitudinal shaft, the shaft being adaptable substantially longitudinally relative to the mortar shell, and a first end of the shaft being supportable to the support element;and a second end of the shaft of the attachment piece including a support portion transversal to the longitudinal axis of the mortar shell for supporting the attachment piece to the front surface of the guiding fin;and the attachment piece including at least one predetermined deformable point allowing a fired mortar shell to be detached from the support member. 2. The support member of claim 1, whose attachment piece includes a predetermined weakened point, at which the attachment piece is arranged to break by the action of forces caused by firing the mortar shell. 3. The support member of claim 1, whereinthe deformable point is arranged in the support portion,and wherein the area of the cross-section at the deformable point is smaller than in other portions of the attachment piece. 4. The support member of claim 1, wherein the support portion or shaft of the attachment piece is arranged to bend relative to each other and to release the attachment between the attachment piece and the guiding fin by the action of forces caused by firing the mortar shell. 5. The support member of claim 1, whereinthe shaft of the attachment piece includes a longitudinal first shaft portion and a second shaft portion,and the second ends of the shaft portions are combined to one another by a transverse support portion, the attachment piece forming a loop that is adaptable around at least one guiding fin. 6. The support member of claim 1, wherein the shaft and support portion of the attachment piece are arranged at one end of the attachment piece substantially T-shaped, whereby the shaft is adaptable between two adjacent guiding fins and the support portion is adaptable against the front surfaces of said adjacent guiding fins. 7. The support member of claim 1, wherein the support member includes a support ring for supporting at least one attachment piece to the sup port element,the support ring includes a front surface, a rear surface and a middle hole provided with first threads,the front surface of the support ring is adaptable on the side of the rear surface of the tail of the mortar shell,the first end of the attachment piece is provided with at least one transverse portion that is supportable against the rear surface of the support ring,the longitudinal axis of the support element is provided with a sleeve having a front surface and an outer circumference provided with second threads, andthe sleeve of the support element is drivable into the middle hole of the support ring, whereby the front surface of the sleeve is arranged to settle against the rear surface of the tail of the mortar shell and pull the support ring and the attachment piece backward for tightening the support member at the tail of the mortar shell. 8. The support member of claim 7, whereinthe support ring includes first positioning members for positioning the support ring at a predetermined position relative to the guiding fins of the tail of the mortar shell,and the outer circumference of the support ring includes second positioning members for positioning each attachment piece at a predetermined position relative to the support ring. 9. A method for attaching a support member to a mortar shell, the method comprising:attaching the support member to the tail of the mortar shell, the support member including a support element provided with a rim flange and a firing mechanism;supporting the support membe r to the front surface of at least one guiding fin at the tail of the mortar shell by means of at least one attachment piece arranged between the support element and said front surface. 10. The method of claim 9, comprising adapting a substantially loop-shaped attachment piece around at least one guiding fin.
