1. A triple security unfolding clasp for holding two ends of a bracelet or strap, said clasp comprising a buckle around both sides of which are hinged a first strand and a second strand, each carrying respectively a first and second shouldered locking pin, and arranged to cooperate in a closing position of said clasp with a complementary locking eye comprised in said buckle, and wherein said buckle includes two pushers, including a first pusher and a second pusher, which can move in a same direction, each against resilient return means returning said two pushers towards a locking position and each of said two pushers arranged to control, directly or indirectly, the forward or backward movement of a first primary bolt and a secondary primary bolt, which are facing each other in said direction with a first secondary opposite bolt and a second secondary opposite bolt controlled by one of said two pushers, each said bolt being arranged to immobilize, in said closing position, at said complementary locking eye, a constricted portion comprised in said locking pin, and an individual travel of each of said pushers is smaller than a release travel during which at least two bolts facing each other release, in an opening position, said constricted portion of at least one of said locking pins, and a cumulated travel of said pushers is greater than or equal to said release travel, wherein said first pusher simultaneously, directly and integrally drives said first primary bolt opposite a first locking pin, and said second primary bolt opposite a second locking pin, whereas said second pusher independently drives a first secondary bolt opposite said first locking pin, and a second secondary bolt opposite said second locking pin, so that only a combined actuation of said two pushers causes the movement of all of the bolts through their entire release travel to release both said first locking pin and said second locking pin, and so that one of said two secondary bolts remains in a locking return position during the insertion of one of said locking pins towards said complementary locking eye corresponding thereto, to a locking position. 2. The triple security unfolding clasp according to claim 1, wherein, when the user exerts pressure, said second pusher is arranged to push, in said direction and via a bearing surface comprised in said second pusher, a first bearing surface of said first secondary bolt, or a first female slide carrying said first secondary bolt and a second bearing surface of said second secondary bolt, or a second female slide carrying said second secondary bolt, so as to move said first secondary bolt and said second secondary bolt parallel to each other. 3. The triple security unfolding clasp according to claim 1, wherein, in the absence of any action by the user on one of the pushers, said first secondary bolt and said second secondary bolt, or a first female slide carrying said first secondary bolt and a second female slide carrying said second secondary bolt can move independently of each other against said resilient return means. 4. The triple security unfolding clasp according to claim 1, wherein, in the absence of any action by the user on one of the pushers, said first secondary bolt and said second secondary bolt can move independently of each other against said resilient return means. 5. The triple security unfolding clasp according to claim 1, wherein a first said complementary locking eye, is delimited by the cooperation of said first primary bolt and said first secondary bolt, and wherein a second said complementary locking eye is delimited by the cooperation of said second primary bolt and said second secondary bolt, and each said complementary locking eye constitutes a chamber of variable volume, between an opening position in which said complementary locking eye is able to let pass a head comprised in said locking pin corresponding thereto, and a closing position in which said complementary locking eye is able to grip said constricted portion of one said locking pin corresponding thereto, between jaws formed by bearing surfaces comprised in said bolts, and immobilizing said head on the opposite side to said strand carrying said locking pin, relative to said jaws. 6. The triple security unfolding clasp according to claim 1, wherein said first pusher, like said second pusher, is moveable in said direction between a first stable rest position of maximum extension relative to said buckle and in which said pusher does not cooperate with any of said locking pins, another second stable intermediate locking position in which said pusher immobilizes at least one of said locking pins, and a third transitory release position under maintained pressure by the user and in which said pusher tends to release said locking pins, said first pusher being moveable from said first stable rest position to said third transitory release position in a first actuating direction, and said second pusher being moveable from said first stable rest position to said third transitory release position in a second actuating direction opposite to said first direction, and wherein said first primary bolt and said second primary bolt each include a bearing surface which is turned towards said first stable rest position of said first pusher, and wherein said first secondary bolt and said second secondary bolt each include a bearing surface which is turned towards said first stable rest position of said second pusher, so that, in the absence of any pressure by the user on at least said first pusher or respectively on said second pusher, said first primary bolt and said second primary bolt, or said first secondary bolt and said second secondary bolt respectively, tend to move closer to said first secondary bolt and said second secondary bolt, or to said first primary bolt and said second primary bolt respectively, in a movement of translation in the opposite direction to said first actuating direction or to said second actuating direction respectively, under the action of said resilient return means. 7. The triple security unfolding clasp according to claim 6, wherein said first stable rest position and said second stable intermediate locking position of said first pusher are the same, and wherein said first stable rest position and said second stable intermediate locking position of said second pusher are the same. 8. The triple security unfolding clasp according to claim 1, wherein the mobility of said first pusher relative to said buckle is limited by the travel of a stop in a chamber, and wherein the mobility of said first secondary bolt and said second secondary bolt relative to said buckle is limited by the travel of a stop in a chamber. 9. The triple security unfolding clasp according to claim 1, wherein the mobility of said second pusher relative to said buckle is limited by the travel of at least one stop in a chamber. 10. The triple security unfolding clasp according to claim 1, wherein said second pusher includes a sliding bearing surface arranged to cooperate with a complementary sliding surface comprised in each of said secondary bolts. 11. The triple security unfolding clasp according to claim 1, wherein said buckle includes bearing surfaces for guiding in translation in said direction, arranged to cooperate with first complementary guide surfaces comprised in said secondary bolts or comprised in slides carrying said secondary bolts, which also include second guide surfaces arranged to cooperate with each other or with a guide element in said direction comprised in said buckle or said second pusher or said first pusher. 12. The triple security unfolding clasp according to claim 1, wherein said first secondary bolt and said second secondary bolt include guide surfaces extending in said direction and arranged to cooperate with complementary guide surfaces comprised in said first pusher in proximity to said first primary bolt and second primary bolt. 13. The triple security unfolding clasp according to claim 1, wherein said first secondary bolt and said second secondary bolt include guide surfaces extending in said direction and arranged to cooperate with an arm comprised in the median part of said first pusher. 14. A bracelet including a clasp according to claim 1.
