Claim 0:
1. A coupling comprising:
a receiving element,
a securing element,
at least one retaining element formed separately from the securing element, and
an insertion element,, wherein the insertion element is insertable into a receiving space of the receiving element along an insertion axis,, wherein the at least one retaining element includes a projection that, when connected to the receiving element, extends radially inwards into the receiving space, wherein a first portion of the projection extends further radially inwards than a second portion of the projection with respect to an inner wall of the receiving space,, wherein the at least one retaining element includes a retaining arm extending parallel to the insertion axis, the retaining arm being resilient in a radial direction with respect to the insertion axis,, wherein the retaining arm has a supported end and a free end, the supported end being resiliently connected to the at least one retaining element and the free end being opposite the supported end with respect to the insertion axis, the free end being received longitudinally deeper within the receiving element than the supported end,, wherein the securing element is adapted to be displaceable along a displacement axis between a release position and a locking position,, wherein the securing element is adapted to engage with the at least one retaining element in its release position, without the insertion element inserted into the receiving space of the receiving element, in such a way that a displacement of the securing element from the release position in a direction of the locking position is prevented,, wherein the insertion element is adapted to interact with the at least one retaining element when the insertion element is inserted into the receiving space of the receiving element, in such a way that a displacement of the at least one retaining element from the release position into the locking position is enabled.
