Abstract: Device to change a glove used for manipulation in confined spaces, including a part to receive the hand in a flexible material, and a ring, on a longitudinal axis, around an opening in the glove for insertion of the hand, with said ring also having means for attachment to an enclosure forming a confined space, said attachment means being designed to be locked and unlocked by application of a substantially axial force, the device including a push device that is intended to be placed on the used glove, and a support that is intended to receive the new glove.

Abstract: To ensure the disconnectable connection of two components with a non-circular outline, in particular an oval outline, a rotatable ring of oval shape is fitted on a first component, cooperating with a second component by a bayonet system. Rotation of the ring is made possible by positioning at least four arc of a circle shaped segments along the desired outline with a space between the ends of adjacent segments. The link between these ends is made by articulated components.
