Abstract:
1. A device for determining at least one parameter of a medium which flows in a conduit, comprising a fluid conduit part having a wall which forms a fluid conduit passage and has an insertion opening; a plug sensor having a sensor element, an insertion portion which is inserted through said insertion opening of said wall into said fluid conduit passage, an electrical connection portion which is not inserted into said fluid conduit passage, and a stop surface arranged so that an insertion movement of said insertion portion is limited by abutment of said stop surface against a stop surface of said fluid conduit part; and mounting means for mounting said plug sensor on said fluid conduit part, said mounting means including a holding part which is pushed substantially perpendicular to an insertion direction of said plug sensor onto a connecting pipe of said fluid conduit part, which surrounds said insertion opening, said holding part having at least one first portion, abutting against a supporting surface of said connecting pipe and at least one second portion applying a pretensioning force caused by said holding part to a securing surface of said plug sensor which faces away from said insertion portion of said plug sensor, so that said stop surface of said plug sensor is pressed against said stop surface of said fluid conduit part, wherein said holding part has at least one leg which engages said securing surface and is inserted substantially perpendicular to an insertion direction of said plug sensor into guiding means of said connecting pipe, wherein said holding part has two said legs which are connected with one another by a connecting web.
