Claim:
A connection system for connecting construction elements suitable for transportation to and use in the construction of buildings, comprising: a retaining element ( 1 a ) integral with a first construction element ( 2 ), the first construction element being a reinforced concrete precast cladding panel; and an anchoring device ( 1 b ) connecting said retaining element to a second construction element ( 3 ), the second construction element being a construction beam, wherein, said anchoring device comprises two wings ( 4 ) connected by a middle part ( 5 ), each of the two wings connected to the second construction element ( 3 ), the two wings each defining an arch with an introdos, the intrados of the two wings ( 4 ) lay on a common first plane, axes of the two wings ( 4 ) lying on the first plane and providing an angle therebetween with a vertex pointing to the first construction element ( 2 ), the middle part ( 5 ) comprising i) a joint area ( 5 a ), ii) an at least partially treaded pin ( 5 b ) joined to the joint area, iii) a block ( 5 c ) provided with a threaded hole, a front end of the pin ( 5 b ) screwed into the threaded hole of the block, and iv) a locking nut ( 5 d ) screwed on the pin ( 5 b , 64 b ), wherein the block ( 5 c ) is located within the retaining element bearing against inner parts of the retaining element counteracting the inner parts in a first direction, and the locking nut ( 5 d ) is screwed on the pin ( 5 b ) against outer parts of the retaining element countering the outer parts of the retaining element in a second direction opposite the first direction so that, during a service life thereof, relative displacements between the first construction element ( 2 ) and second construction element ( 3 ) on the first plane where the axes of the two wings ( 4 ) lie are prevented.
