Abstract
A connection assembly for fastening an attaching element on a support (10) comprises a holding clip (16), which can be inserted into a mounting opening (20) of the support (10) and has holders (54) for axially fixing the holding clip (16) to the support (10), and a pin (12), which can be reversibly attached to a coupling piece (14) fastened to the attachment element and inserted into the holding clip (16). The pull-off force of the pin (12) in an intermediate position of the connecting assembly, in which the pin (12) has a first orientation relative to the holding clip (16), is larger than in a mounting position of the connection assembly, in which the pin (12) also has the first orientation and is inserted fully into the holding clip (16).
Claims10
A connecting assembly for fastening an add-on element on a carrier (10), comprising
- a holding clip (16) which can be inserted into a mounting opening (20) of the carrier (10) and includes holding means (54) for axially locating the holding clip (16) on the carrier (10), and
- a pin (12) which can be reversibly fitted to a coupling part (14) fastened to the add-on element and can be inserted into the holding clip (16),
- the removal force of the pin (12) being larger in an intermediate position of the connecting assembly, in which the pin (12) has a first orientation relative to the holding clip (16) and is not completely inserted in the holding clip (16), than in a mounting position of the connecting assembly, in which the pin (12) likewise has the first orientation and is completely inserted in the holding clip (16),
- the pin (12) including first retaining means (30) formed as undercuts having holding surfaces (36) that are oriented substantially perpendicularly to a longitudinal axis (A) of the pin (12), the first retaining means (30) in the intermediate position cooperating with complementary retaining means (64) of the holding clip (16), wherein in the intermediate position the pin (12) is transferred to a second orientation having a different angle of rotation relative to the longitudinal axis (A) of the pin (12) than the first orientation such that the first retaining means (30) ceases cooperation with the complementary retaining means (64) when transferred from the first orientation to the second orientation, rotation of the pin (12) relative to the holding clip (16) when the pin is in the intermediate position causing the first retaining means (30) of the pin (12) to move out of engagement with the retaining means (64) of the holding clip (16) to allow for removal of the pin (12) from the holding clip (16),
- the pin (12) including second retaining means (32) having upper and lower ramps (38) that converge towards one another in a direction extending towards the longitudinal axis (A) of the pin (12) to form notches, the notches of the second retaining means (32) in the mounting position cooperating with the complementary retaining means (64) of the holding clip (16).
