1. A device for suspending an airplane turbojet, wherein the airplane turbojet is connected to a pylon fastened to a structure of an airplane by attachments including hinged links, each attachment connecting the pylon to a casing of the airplane turbojet, wherein at least one of the attachments comprises a pin support for a pin fastened to the pylon, and including first, second, and third spaced-apart branches including passages through which the pin passes,the first, second, and third branches are arranged side-by-side and are fastened to the pylon such that the pin is oriented parallel to a direction that is tangential to the casing,wherein the pin is hinge-mounted by a ball joint to the first branch of the pin support, the first branch being a central branch,wherein the pin passes through the second and third branches with clearance,wherein two of the hinged links are arranged symmetrically about a midplane of the pin support and are hinged-connected to the casing and to the pin, andwherein the pin support is defined using three identical parts arranged side by side, each part including a first portion and a second portion, the second portion of each of the parts defining one of the first, second, and third branches. 2. A device according to claim 1, wherein said two of the hinged links are connected directly to the pin by a ball joint. 3. A device according to claim 2, wherein each ball joint providing a hinge connection for each of said two of the hinged links to the pin is situated in a vicinity of a corresponding end of the pin and on a side of one of the second and third branches that is remote from the first branch of the pin support. 4. A device according to claim 1, wherein two passages in the second and third branches situated on either side of the first branch are bores, and bushings of selected thickness are mounted in the bores to determine a desired clearance between the pin and each of the second and third branches. 5. A device according to claim 1, wherein the pin comprises a tube including two segments of different diameters defining a shoulder in a central portion, wherein the shoulder forms a first abutment for positioning the ball joint of the first branch, wherein a smaller-diameter segment is covered by a sleeve forming a second abutment for positioning the ball joint of the first branch, with the tube, the ball joint, and the sleeve, being held assembled together by axial bolting passing through the tube. 6. A device for suspending an airplane turbojet, wherein the airplane turbojet is connected to a pylon fastened to a structure of an airplane by attachments including hinged links, each attachment connecting the pylon to a casing of the airplane turbojet, wherein at least one of the attachments comprises a pin support for a pin fastened to the pylon, and including first, second, and third spaced-apart branches including passages through which the pin passes,the pin support being fastened to the pylon such that the pin is oriented parallel to a direction that is tangential to the casing,wherein the pin is hinge-mounted by a ball joint to the first branch of the pin support, the first branch being a central branch, wherein the pin passes through the second and third branches with clearance, and wherein two of the hinged links are arranged symmetrically about a midplane of the pin support and are hinged-connected to the casing and to the pin, andwherein the pin comprises a tube including two segments of different diameters defining a shoulder in a central portion, wherein the shoulder forms a first abutment for positioning the ball joint of the first branch, wherein a smaller-diameter segment is covered by a sleeve forming a second abutment for positioning the ball joint of the first branch, with the tube, the ball joint, and the sleeve, being held assembled together by axial bolting passing through the tube.
