A preassembled mechanical pipe coupling for joining pipe elements in end-to- end relationship is disclosed. The coupling is formed from a plurality of interconnectable segments that are initially maintained in spaced apart relation. The segments have arcuate surfaces that project inwardly. Connection members in the form of lugs and fasteners are mounted on the segments. The connection members are adjustably tightenable for drawing the coupling segments together and forcing the arcuate surfaces into engagement with the outer surfaces of the pipe elements. Notches are formed at ends of the arcuate surfaces to provide clearance allowing the pipe elements to be inserted between the segments when they are in the pre-assembled, spaced apart configuration.

Est présenté un couplage de conduite mécanique pré-assemblé pour rejoindre des éléments de conduite dans une relation de bout en bout. Le couplage est formé à partir de plusieurs segments raccordables, initialement espacés. Les segments possèdent des surfaces curvilignes qui se projettent vers l'intérieur. Les éléments de connexion en forme de tenon et de fixateur sont fixés sur les segments. Les éléments de connexion peuvent être resserrés fermement pour rapprocher les segments de couplage et obliger les surfaces curvilignes à s'engager avec les surfaces extérieures des éléments de conduite. Les entailles sont formées aux extrémités des surfaces curvilignes pour fournir un espacement permettant d'insérer les éléments de conduite entre les segments lorsqu'ils sont en configuration de séparation en pré-assemblage.
