A valve comprising a body permanently fixed to a pipe, a plurality of assemblies separable from the body by translation movements substantially perpendicular to the pipe and including: a first assembly incorporating an operating member for the valve, a second assembly located opposite to the first assembly with respect to the body, wherein the second assembly is made of a first component connected to the body and a second component movable relatively to the first component in one mounting and dismantling direction, the second component comprising opposite surfaces which impinge on the first assembly so as to lock said first assembly on the body and release said first assembly from the body when the second component is moved, and stop means on the body for preventing the first assembly from being disengaged from the opposite surfaces when the first assembly is locked while allowing disengagement when the first assembly is released.
