ABSTRACT:
An object-holding device is described wherein a cup component comprising an elastically deformable sucker cup and an associated air vent passage communicating with the cup interior is urged by spring means into a position in which the end of such passage remote from the sucker cup is closed off by a selaing element on a supporting body in which the cup component is mounted for limited axial movement. For releasing an object held by the cup after the latter is pressed against the object, the body and cup component have merely to be relatively displaced against the spring bias to unseal the vent passage.
