A device for the connection and the locking of two parts (30a, 30b), including a female part (10) comprising two bars (12), a male part (21) cooperating with this female part (10), and a hinged flap (17). Each bar (12) contains two balls (2a, 2b) and at least one movable inner stop (5) arranged between the balls (2a, 2b). The axial length of the movable stop (5) plus the diameters of the two balls (2a, 2b) is greater than the distance between the two lateral faces of the branch (11a, 11b) in which the ball bar (12) is situated. Also provided is a method for the connection and the locking of two parts, a ball bar, and a method for producing the latter and to the uses thereof.

1. A device for the connection and the locking of two parts, comprising: a U-shaped female part provided with a bar on each branch of the U-shaped female part;a male part comprising an end capable of being inserted into an opening of the female part and of cooperating with the two bars of the female part;a hinged flap capable of cooperating with each bar; the hinged flap being mounted on the female part or the male part; wherein each bar contains two balls each arranged at a respective end thereof;at least one movable inner stop arranged between the balls;the axial length of the movable stop plus the diameters of the two balls being greater than the distance between two lateral faces of the branches in which the bar is situated. 2. The device as claimed in claim 1, in which each bar comprises at least one elastic means separating the balls from one another. 3. The device as claimed in claim 2, in which the elastic means is a helical spring and the movable inner stop is arranged inside this helical spring. 4. The device as claimed in claim 1, in which the hinged flap comprises a plate provided on its lateral sides with tabs which are flat, perpendicular to the plate and which are each provided, on their face directed toward the other tab, with a notch capable of receiving a ball of one of the bars. 5. The device as claimed in claim 4, in which the axial length of the movable inner stop of each bar is chosen such that each of the balls can retract fully into the ball bars but such that it is impossible for the two balls to retract at the same time fully into the bar. 6. The device as claimed in claim 1, in which the hinged flap is fastened on the female part. 7. The device as claimed in claim 1, in which the female and male parts are connected respectively to the two ends of a necklace, of a belt or to two strands of a bracelet. 8. A method of connecting and of locking two parts by means of a device as claimed in claim 1, comprising the following steps: the hinged flap is opened;the end of the male part is introduced into the opening of the female part until a first snap-fastening is produced; andthe hinged flap is swiveled in the direction of the bars until a second snap-fastening is produced. 9. A ball bar comprising: a hollow part of elongate shape, the longitudinal ends of said elongate shape being drawn in;two balls arranged inside the hollow part of elongate shape, at each of its longitudinal ends; andat least one movable inner stop arranged inside the hollow part of elongate shape, between the balls, wherein the axial length of the movable inner stop is chosen such that when one of the balls is fully retracted into the hollow part of elongate shape, it is impossible for the other ball to retract fully into the ball bar. 10. The ball bar as claimed in claim 9, of which the hollow part of elongate shape is a hollow cylinder. 11. The ball bar as claimed in claim 9, additionally comprising an elastic means. 12. The ball bar as claimed in claim 11, in which the elastic means is a helical spring. 13. The ball bar as claimed in claim 12, in which the movable inner stop is arranged inside the helical spring. 14. The ball bar as claimed in claim 9, of which the movable inner stop takes the form of a pin. 15. A method of producing a ball bar as claimed in claim 9, comprising a step during which a movable inner stop is introduced into the hollow part of elongate shape. 16. A device comprising at least one ball bar as claimed in claim 9. 17. The use of a ball bar as claimed in claim 9 for the connection and/or the locking of parts.
