Abstract

The invention relates to a mobile station which can be attached to a target, removed from it and re-attached to it by use of an attachment device which comprises: a support stud (2) attached to a mobile station with a fitting piece (3); and a carrying device (1) in the target, having elements for the detachable grip on the support stud. The fitting piece is formed of a U-shaped plate (4) having a first branch (5a) on the outer surface of which said support stud is located and a second branch (5b) which in the operating state is located in an attachment cavity (6) of the rear cover (22) of the mobile station. The first branch of the U-plate rests against the outer surface (21) of the rear cover of the mobile station (20) and the second branch rests against the inner surface (23) of the rear cover.

6. A fitting piece in a mobile station according to claim 5 characterized in that there is, on the second surface (23) of the rear cover, at a distance (S), which corresponds to the distance of the tongue or projection (14) in the second branch of the fitting piece from the bottom (7) of the U-shape, from the rear cover edge (12) facing the power supply part, a hollow (15) into which the tongue or projection (14), which faces the first branch and is located at or near the outer edge of the second branch (5b) of the U-shape of the fitting piece (3), can snap to lock the fitting piece into its place.

7. A fitting piece in a mobile station according to claim 6, characterized in that the power supply part (24) locks the fitting piece (3) irremovably into its place, to which end the power supply part is located against the bottom (7) of the U-plate (4) of the fitting piece on the side opposite to the opening direction of the U-shape, and that the power supply part is a power supply assembly.

8. A fitting piece according to claim 1, characterized in that the target to which the mobile phone (20) is attached to a carrying device, and that the carrying means (1) is attached to a target.

9. In a mobile phone assembly which, by means of an attachment device, can be attached to a target and detached therefrom and re-attached thereto, the attachment device comprising:

a support stud (2) attached to a mobile phone with a fitting piece (3); and
