A device 7 for the assembly of a straight spigot 1 and a flange 3 of two pipe elements 2, 4, containing an axial compression sealing elastomer gasket 8. The gasket has a support body 15 bearing against a counter flange 11 to apply pressure to the gasket. To the front of the body 15, and interdependent of it, is a support heel 16 for bearing against the flange. A radial exterior surface 22 of the body is designed to rest on a reaction surface 27, 27a of the counter flange, a radial interior surface 18 of the body is designed to rest on the radial exterior surface 20 of the straight spigot, and a forward surface 31 of the heel is designed to press against the flange to insure the waterproofness of the assembly. The body has at least one recess 26 for the expansion of the elastomer of the pressurized gasket, and the device is fitted with a ring 9 to limit the radial expansion of the heel toward the exterior.
