The invention refers to an arrangement for the leading-in of a pipe (17) through a recess (16) in walls (18) or vaults in buildings with the help of a case (1) enclosing the pipe (17). The case (1) is extended along the recess (16), and has at least at a first end a thread (2) and is at least at the mentioned first end furnished with a detachable screwed-on collar (6, 6') for the fixation of the case (1) to the wall (18). The collar (6, 6') has a collar ring (10, 10') with a hole (11, 11') through which the pipe (17) is extended and whose diameter is essentially in accordance with the pipe (17). The case (1) is elastic and less stiff than the collar (6, 6'). |
