1. A locking device designed for fixedly attaching a first element to a second element, said locking device comprising: a locking member intended for equipping the first element,a complementary locking member intended for equipping the second element, anda control handle connected to the locking member by transmission means, characterized in thatwherein the transmission means comprise a telescopic connecting rod designed to oscillate freely between a position of minimum extension and a position of maximum extension and, on the-other-hand, means for the return of the telescopic connecting rod toward a position of maximum extension, said return means being placed in a prestressed state when the control handle is in the closing position. 2. The locking device as claimed in claim 1, wherein the telescopic connecting rod comprises a first rod fitted into a second rod. 3. The locking device as claimed in claim 2, wherein the return means comprise at least one spring integrated in the telescopic connecting rod. 4. The locking device as claimed in claim 3, thatwherein the spring has a first end fastened in an end of the first rod fitted in the second rod, and a second end fastened in the second rod. 5. The locking device as claimed in claim 2, wherein a pin fastened transversely in the second rod passes through two slots formed in a lateral surface of the first rod. 6. The locking device as claimed in claim 1, wherein the control handle is designed so as to be capable of being displaced alternately from a stable opening position, in which the locking member is open, to a stable locking position, in which the locking member is closed, passing through an unstable intermediate phase where the locking member is closed. 7. The locking device as claimed in claim 6, wherein the return member is designed so as to be capable, during the intermediate phase, of returning the control handle in the direction of its opening position if said control handle is freed of any external stress. 8. A turbojet engine nacelle comprising: a front air inlet section,a middle section intended for surrounding a blower of the turbojet engine, anda rear section formed from at least two half-shells held in a closing position by means of locking assemblies arranged along a junction line located in the lower part,wherein at least one of these locking assemblies comprises a locking device as claimed in claim 1. 9. The turbojet engine nacelle (1) as claimed in claim 8, wherein at least the locking device is arranged in front of the junction line. 10. An aircraft, comprising at least one nacelle as claimed in claim 8.
