Device for condom fitting, in its one-cylinder from encloses cylinder (2) with free frontal opening (6) and with a fixed ring (5) with groove (15) for receiving cover (20), whereby groove (15) is continued by neck (14), finished by rib (7), whereby the hind opening (8) of ring (5) is closed by a fastened flat membrane (22) or a spherical concave membrane (22a), with or without the handle (21), while the internal space of device (1) is connected to atmosphere through valve (9a) or (10b). Device (1) in multi-cylinder, primarily three-cylinder realization form, encloses the first cylinders (2a,2c) with free frontal opening (6) with neck (14), finished by ribs (7), as well as fixed ring (5) with groove (15), and also with the telescopically sealed placed second cylinder (3) and the third cylinder (4) with closed bottom (4a), whereby on the ends of the coupled cylinders (2a,2c,3,4) internal ribs (19a) as well as external ribs (19b) are executed, for leaning onto the sealing rings (11) for preventing undesired dismantling of device (1). Device (1) encloses also free, limitedly turnable and axially moved ring (5c) in variant realization, same as sealing rings (11a,11b). |
