A latch arrangement for fastening a panel of a door or a window to a frame element is provided. The latch arrangement includes a locking element mounted on the frame element and displaceable between a locked position in which the locking element can be engaged with a depression formed on the panel locking thereby the panel to the frame element, and an unlocked position in which the locking element can be disengaged from the depression on the panel unlocking thereby the panel from the frame element; an actuating mechanism including a manually operable handle, the actuating mechanism being mounted on the panel and being configured to selectively engage the locking element and to displace the locking element away from the depression to the unlocked position.

1. A latch arrangement for fastening a door or window panel to a frame element, the latch arrangement comprising: a locking element mounted on the frame element and displaceable between a locked position in which said locking element is engaged with a surface rigidly defined on the panel thereby locking the panel to the frame element, and an unlocked position in which said locking element is disengaged from the surface thereby unlocking the panel to allow opening of the panel without movement of the frame element;an actuating mechanism mounted on the panel and configured to selectively engage said locking element and to displace said locking element out of engagement with the surface to said unlocked position,wherein said locking element is mounted on the frame element so as to undergo motion comprising a rotary motion between said locked position and said unlocked position, and wherein said actuating mechanism is configured to selectively move said locking element to said unlocked position. 2. The latch arrangement according to claim 1 wherein said actuating mechanism comprises a handle displaceably mounted on the panel so as to be displaceable between a first position in which said actuating mechanism urges said locking element out of engagement with the surface and a second position in which said actuating mechanism allows said locking element to engage the surface. 3. The latch arrangement according to claim 2 wherein in said first position said handle is pivoted towards an opening direction of the panel. 4. The latch arrangement according to claim 2 wherein said actuating mechanism includes an actuating member displaceably mounted on the panel and configured to selectively move towards said locking element whereby said locking element is displaced to said unlocked position. 5. The latch arrangement according to claim 4 wherein said handle includes a portion engaging said actuating member, and wherein said handle is configured such that, when said handle is displaced to said first position, said actuating member is displaced towards said locking element whereby said locking element is displaced to said unlocked position. 6. The latch arrangement according to claim 5 wherein said handle includes a panic bar configured to pivot towards the panel and a sloped member configured to pivot with said panic bar, said sloped member being configured to engages said actuating member, and wherein when said panic bar is pivoted towards the panel said sloped member is configured urge said actuating member to move towards said locking element. 7. The latch arrangement according to claim 4 wherein said actuating member is configured to move across at least part of a thickness dimension of the panel. 8. The latch arrangement according to claim 1 wherein said locking element in said locked position extends at an oblique angle with respect to the panel such that a first region of the locking element is deployed to engage the surface while a second region of the locking element is supported by the frame element, and wherein in said locked position displacement of the panel towards an opening direction of the panel is opposed by compressive forces exerted on said locking element. 9. A latch arrangement for fastening a door or window panel to a frame element, the latch arrangement comprising: a locking element mounted on the frame element and displaceable between a locked position in which said locking element is engaged with a surface rigidly defined on the panel thereby locking the panel to the frame element, and an unlocked position in which said locking element is disengaged from the surface thereby unlocking the panel from the frame element;a stop latch associated with said locking element and configured to be selectively displaced between a secured position in which said locking element is secured in said locked position, and a released position in which said locking element is free to displace to said unlocked position;an actuating mechanism configured to selectively displace said stop latch to said released position and to displace said locking element to said unlocked position,wherein said actuating mechanism is mounted on the panel. 10. The latch arrangement according to claim 9 wherein said actuating mechanism comprises a manually displaceable handle displaceably mounted on the panel, and wherein the actuating mechanism is configured such that motion of said handle performs sequentially release of said stop latch following by a displacement of said locking element out of engagement with said surface. 11. The latch arrangement according to claim 10 wherein said stop latch is mounted on said locking element and is configured to selectively engage an abutment feature such that displacement of said locking element to the unlocked position is precluded. 12. The latch arrangement according to claim 11 wherein said stop latch is slidably mounted on said locking element and is configured to slide between a secured position in which at least one portion thereof is engaged with said abutment feature and a released position in which said at least one portion is retracted away from said abutment feature such that said locking element is free to be displaced to said unlocked position. 13. The latch arrangement according to claim 12 wherein said abutment feature is defined on the panel. 14. The latch arrangement according to claim 11 wherein said stop latch is pivotally mounted on said locking element and is configured to pivot between a secured position in which said locking element is secured in said locked position and a released position in which said locking element is free to be displaced to said unlocked position, and wherein said actuating mechanism is configured to selectively pivot said stop latch to said released position. 15. The latch arrangement according to claim 14 said abutment feature is defined on the frame element. 16. The latch arrangement according to claim 14 wherein said actuating mechanism includes a catch member and wherein in said secured position said stop latch is engaged with said catch member. 17. A panel closure comprising: a frame element;a panel configured to abut against a portion of said frame element; andthe latch arrangement of claim 1, deployed to selectively fasten the panel to the frame element. 18. The panel closure of claim 17, wherein said panel is a sliding panel configured to slide towards and away from said frame element, between a closed state and an open state. 19. The panel closure of claim 17 wherein said panel is a hinged panel configured to rotate towards and away from said frame element, between a closed state and an open state. 20. A latch arrangement for fastening a door or window panel to a frame element, the latch arrangement comprising: a locking element mounted on the frame element and displaceable between a locked position in which said locking element is engaged with a surface rigidly defined on the panel thereby locking the panel to the frame element, and an unlocked position in which said locking element is disengaged from the surface thereby unlocking the panel from the frame element;an actuating mechanism mounted on the panel and configured to selectively engage said locking element and to displace said locking element to said unlocked position,wherein said locking element in said locked position extends at an oblique angle with respect to the panel such that a first region of the locking element is deployed to engage the surface and a second region of the locking element is supported by the frame element, and wherein in said locked position displacement of the panel towards an opening direction of the panel is opposed by compressive forces exerted on said locking element.
