Said elastically deformable means (15) is constituted by a tube made from an elastically deformable material.

Each resiliently deformable member is movable relative to an immediately adjacent resiliently deformable member.

The sheet (12) is elastically contracted.

The projections (13) are elastically deformable.

A spring resiliently supports the cage.

The slot (32) is resiliently compressible.

The end (13) is therefore elastically deformed.

In some embodiments, a portion of the retainer is resiliently deformable, and at least partially defines the resiliently deformable connection.

The lateral arms thereof remain elastically deformable.

The elastically deformable element is elastically deformable for disengaging the engaging lip (8) or engaging edge (12).

The bistable element may be designed for example as an elastically deformable rod (1) or as an elastically deformable leaf spring.

An elastically deformable process target is elastically deformed in an inplane direction from a first state.

The funnel (9) is made of an elastically deformable material.

An elastically deformable holder has a holder body made of an elastically deformable material such as, for example, a shape memory alloy, that deforms elastically in response to an application of force.

The two legs (2a, 2b) are elastically deformable in a radial direction in order to be elastically adaptable on the supporting frame (1).
