Title: Tool for fitting a resilient ring into a groove

Abstract: A tool comprising a receptacle having a cylindrical portion defining a space therewithin adapted to receive a resilient seal after deformation of the latter by an external member is disclosed. A movable member carried by said receptacle comprises a tubular portion slidably received on the cylindrical portion and movable from a first position in which said tubular portion is opposite the space towards a second position in which said tubular portion is offset relative to the space against the action of a first spring. The tubular member is provided with an aperture adapted to receive the external member, and an element is slidably carried in said space and resiliently urged away from the latter by a pair of second springs, thereby expulsing the seal in a corresponding groove when the tubular member is moved towards its second position.
