A collar device for the wall mounting of pipes and the like consists of two half-collars with a semi-circular profile (1, 1'), of which a first profile (1) is centrally provided with a hole (2) flared outwards whereas a second profile (1') has no hole, and at the ends of said profiles (1, 1') there are provided coupling elements consisting at a first end of the semi-circular profile (1, 1') of a first flat segment (3) and at the other end of a similar flat segment (3') that continues in a subsequent segment (5) bent 180 DEG inward, so as to form between said segments (3', 5) a U-shaped seat arranged in the same plane of the first flat segment (3) and suitable to receive the latter. In this way the possibility is achieved of a partial mounting of the pipe (T) thanks to the initial manual locking of the device by relative longitudinal sliding of the two half-collars, so that the position of the pipe (T) can be precisely adjusted though assuring a secure support even before the complete locking. Furthermore, the manufacturing process is simplified with respect to prior art collars, since no welding nor threading step is required but only a simple forging of both half-collars by means of a single die. <IMAGE> |
