Abstract
A connector including two interfitting tubular elements and a locking ring having at least two staggered rows of locking lugs cooperating with corresponding locking lugs of one of the tubular elements. The locking lugs are inscribed in cylindrical surfaces having different radii, so that when the ring is inserted on the element, its lugs slide effortless on the lugs of the first lug row of the element to a position where the lugs of each lug row of the ring can pass between those of a corresponding row of the element to form a plurality of bayonet couplings which can then be simultaneously locked.
