Sleeve for the Guiding-Through of at Least One Line

A method for guiding a line surrounded by a sleeve through a mounting opening of a component, the sleeve having a hose-like center section and at least one end-side head section insertable into the mounting opening, the method comprising the acts of:

• guiding the line with the surrounding sleeve through the mounting opening;
• inserting the head section into the mounting opening;
• placing a reinforcing part around the line by moving the reinforcing part in a radial direction toward the line;
• and
• inserting the reinforcing part into the head section by moving the reinforcing part in an axial direction of the line.

A method for facilitating mounting of a head section of a sleeve usable for guiding a line through a mounting opening, the method comprising the acts of:

• guiding a line together with the sleeve in a first direction through the mounting opening such that the head section of the sleeve is inserted into the mounting opening;
• after the guiding of the line together with the sleeve and the insertion of the head section in the mounting opening, placing a reinforcing part on the line from a radial direction relative to an axial length of the line, wherein the reinforcing part is divided into at least two mutually displaceable sections;
• after placing the reinforcing part on the line from the radial direction, guiding the two mutually displaceable sections together to form an open ring;
• and
• after forming the reinforcing part as the open ring on the line, inserting the reinforcing part in a second direction opposite the first direction into the head section of the sleeve within the mounting opening.
