<p>The invention involves a socket comprising a sole-plate (22) suitable for fixing thereof to an arbitrary support. According to the invention, this sole-plate (22) extends, inside its periphery, over at least two different levels (I, II), so that, over its rear face, it forms a clearance (28), in that, over its front face, it carries, inset relative to its periphery, wall elements (30) delimiting therein at least one compartment (31, 32), with at least one passage (36) making the clearance (28) communicate with this compartment (31, 32), and in that it has, between these wall elements (30) and the periphery thereof, at least one opening (38) through which the clearance (28) communicates moreover with the peripheral volume (33) outside the said compartment (31, 32). Application, in particular, to alarm posts. <IMAGE></p> |
