FIELD: construction.
SUBSTANCE: tool (100, 400) comprises a working device (102), the handle (104) and the coupling device (108) adapted for attaching the working device to the handle detachably. The coupling device comprises a first connecting portion (110, 424), the second connecting portion (114), the locking element (116) and the cover (120, 410). The first portion has a recess (112). The second connecting portion (114) is configured with the possibility of at least partial reception of the first connecting portion (110, 424). The locking element is configured with the possibility to interact with the recess of the first connecting portion for connecting the handle to the working device detachably. The locking element includes an actuating element (118, 404) which at least partially protrudes from the outer surface (132, 405) of the handle (104) and / or second connecting portion (114). The cover is configured with the possibility to at least partially cover the first connecting portion adjacent to the recess and in addition, with the possibility to at least partially cover the handle (104) and / or second connecting portion (114). The cover (120, 410) includes the first opening (216) and the second opening (218). The first opening (216) is the end opening. The second opening (218) is a side opening located next to the first opening. The first opening and the second opening (216, 218) allow the cover (120, 410) not to impede the connection and disconnection of the second connecting portion.
EFFECT: invention improves the reliability of fastening the working device to the handle.
