said second strip ( 4 ) comprises a loop member ( 28 ) at its second end defining a passage for a second bracelet strand, and carrying a stud ( 30 ) intended to be inserted into a suitable hole in the second bracelet strand to define an anchoring point thereof to the bracelet clasp ( 1 ),
the bracelet clasp ( 1 ) further comprising at least one locking member ( 11 ) that is configured to hold said first strip ( 2 ) and said second strip ( 4 ) in their closed position,
said stud ( 30 ) is movable with respect to the loop member ( 28 ) and includes actuation means ( 34 ) that is configured to be actuated such that the stud ( 30 ) is able to move between at least two predefined positions associated with a predefined useful bracelet length,
said stud ( 30 ) includes a base ( 31 ) integral therewith, said base ( 31 ) being arranged to move in a housing ( 32 ) of the loop member ( 28 ), and
the loop member ( 28 ) includes an oblong recess ( 40 ), said stud ( 30 ) passing through said oblong recess ( 40 ) and the base ( 31 ) coming into contact with the oblong recess ( 32 ).

2. The bracelet clasp ( 1 ) according to claim 1 , characterized in that the housing ( 32 ) formed in the loop member ( 28 ) includes at least one stop member ( 35 ) for holding the stud ( 30 ) in place.

3. A wristwatch including a bracelet provided with the bracelet clasp ( 1 ) according to claim 1 .

4. A bracelet clasp ( 1 ), of a deployant buckle type, comprising:
a first strip ( 2 ) and a second strip ( 4 ) articulated to each other, by a first of their respective ends, such as to be configured to move between a closed position for wear and at least one open position,
wherein said first strip ( 2 ) carries a member ( 20 ) that is configured to attach a first bracelet strand,
said second strip ( 4 ) comprises a loop member ( 28 ) at its second end defining a passage for a second bracelet strand, and carrying a stud ( 30 ) intended to be inserted into a suitable hole in the second bracelet strand to define an anchoring point thereof to the bracelet clasp ( 1 ),
the bracelet clasp ( 1 ) further comprising at least one locking member ( 11 ) that is configured to hold said first strip ( 2 ) and said second strip ( 4 ) in their closed position,
said stud ( 30 ) is movable with respect to the loop member ( 28 ) and includes actuation means ( 34 ) that is configured to be actuated such that the stud ( 30 ) is able to move between at least two predefined positions associated with a predefined useful bracelet length,
said stud ( 30 ) includes a base ( 31 ) integral therewith, said base ( 31 ) being arranged to move in a housing ( 32 ) of the loop member ( 28 ), and
the loop member ( 28 ) includes a cover arranged to cover the housing ( 32 ) and to cooperate with the base ( 31 ) of the stud ( 30 ), the stud and the base each comprising complementary guide means.

5. The bracelet clasp ( 1 ) according to claim 4 , characterized in that the cover ( 29 ) includes a recess ( 42 ) arranged to be placed facing the housing ( 32 ) such as to form a space in which the base ( 31 ) of the stud ( 30 ) moves.
