An underwater connection installation (26) and a laying method for connecting a riser and a flexible pipe (22) that are intended for carrying hydrocarbons. A post (28) is attached to a float (20) to suspend the riser (12) below the surface. The post (28) supports a gooseneck shape pipe (54) that has a bent-over outlet free end (58) ending in a first coupling (60). A coupling end piece (32) mounted on the said flexible pipe (22) includes a second coupling (86). The coupling end piece (32) and the post (28) define mechanical guides including complementary frustoconical rings (64, 84). The driving of the coupling end piece (32) and of the bent-over free end (58) toward each other causes the frustoconical rings (64, 84) to engage one another to bring about coaxial alignment of the couplings (60, 86).
