A plug-in coupling for releasably mounting a first member to a second member, the coupling including a projection having a ball-shaped head and being interconnectable with the first member;
- and an insert member;
- said projection further being insertable into said insert member which said insert member is insertable into a socket at said second member by a snap-in action, said insert member being elastomeric and deformable, said insert member including a cup-shaped female portion insertable into said socket provided at said second member so as to be positively retained in said socket, said insert member further including a cylindrical outer wall adapted to engage a wall of said socket, and said cup-shaped female portion being connected to said cylindrical outer wall by a conical guide portion, and wherein said insert member includes a gap between said cylindrical outer wall and said female portion and said gap includes cordal webs therein including radial ribs as stiffening means which the female portion is supported against and which are arranged to dampen vibrations in all directions.
A plug-in coupling for releasably mounting a first member to a second member, the coupling including a projection having a ball-shaped head and being interconnectable with the first member;
- and an insert member;
- said projection further being insertable into said insert member which said insert member is insertable into a socket at said second member by a snap-in action, said insert member being elastomeric and deformable, said insert member including being cup-shaped female portion insertable into said socket provided at said second member so as to be positively retained in said socket, said insert member being insertable axially into said socket, said insert member being positively retained in said socket by a snap-in action when said insert member is being inserted into said socket, and said socket including a cylindrical wall having, at an open end thereof, a radially inwards extending circumferential rim, and said insert member including an annular groove for snap-in receipt of said circumferential rim.
A plug-in coupling for releasably coupling a first member and a second member, said plug-in coupling comprising:
- a projection fixedly attachable to said first member and including a ball-shaped head, and
- a socket attachable to said second member, and
- an insert member positively retained in said socket and including:
- a cup-shaped female portion which is deformable so as to snappingly receive said ball-shaped head,
- a conical guide portion integral with said female portion, and
- a cylindrical outer wall integral with said conical guide portion such that there is a gap between said cylindrical outer wall and said female portion, said gap further extending between said cylindrical outer wall and at least a part of said conical guide portion.
