TOOL FOR CONNECTION OF A PLASTIC PIPE OR OF A COMPOSITE METAL-PLASTIC PIPE TO A FITTING BY WAY OF A SLIDING SLEEVE OR COMPRESSION SLEEVE Russian patent published in 2018 - IPC B25B27/10 

FIELD: molding.

SUBSTANCE: present invention relates to tool (1) for the connection of a plastics pipe or of a composite metal-plastic pipe to a fitting by way of a sliding sleeve or compression sleeve. Tool (1) for connecting a plastic pipe or a metal-plastic composite pipe to a fitting by way of a sliding sleeve comprises expanding device (3) with first piston-cylinder unit (6), working piston (8) of which has piston axis (9) and inner end (10) and end (11) facing away of tool (1). Sliding device (4) comprising second piston-cylinder unit (12), working piston (13) of which has second piston axis (14), with inner end (15) and end (16) directed from tool (1). Piston axes (9, 14) pass parallel to each other, and the vertical projection of the inner end of expanding device (3) to piston axis (14) of sliding device (4) is placed between inner end (15) and end (16) of sliding device (4) opposite to tool (1), and/or the vertical projection of inner end (15) of sliding device (4) to piston axis (9) of expanding device (3) is placed between inner end (10) and end (11) of expanding device (3), directed from tool (1).

EFFECT: technical result is the possibility of using a tool in cramped conditions and saving time during connection.
