The invention relates to a device for connecting a pneumatically or hydraulically operated tool to a connection coupling in order to provide the connection to a transport line which guides a liquid or gaseous medium. The invention is characterised by an anti-vibration fitting for connecting a vibrating pneumatic or hydraulic tool with an intermediate coupling attached to a fluid feed line, comprising: a first part provided with an adapter section designed to permit insertion in and releasable connection with a port in the intermediate coupling, and a first sleeve; a second part provided with a connector section for rigid connection with the vibrating pneumatic or hydraulic tool, and a second sleeve, wherein the first and second sleeves form an inne r sleeve and an outer sleeve respectively with a space therebetween; and an elastic junction layer comprising an elastic, rubber-like material provided in the space therebetween, wherein th e inner sleeve, the elastic junction layer and the outer sleeve form a common through-hole in th e form of a smooth bore. The elastic junction layer can be produced by casting, injecting or extruding the elastic, rubber-type material between the inner and outer sleeves.
